                                       _________________

       SUTTON, Circuit Judge. David and Pamela Herr bought lakefront property on Crooked
Lake in the Upper Peninsula of Michigan, hoping to use the lake’s waters for recreational
boating and fishing. The United States Forest Service had other plans. Most of Crooked Lake
lies in the federally owned Sylvania Wilderness yet some of it remains under private ownership.
Congress gave the Forest Service authority to regulate any use of Crooked Lake and nearby lakes
“subject to valid existing rights.”     The Forest Service promulgated two regulations, one
prohibiting gas-powered motorboats, the other limiting electrically powered motorboats to no-
wake speeds throughout the wilderness area. Both regulations exceed the Forest Service’s power
as applied to the Herrs and the other private property owners on the lake. Under Michigan
riparian-rights law, in truth littoral-rights law, lakeside property owners may use all of a lake,
making the Herrs’ right to use all of the lake in reasonable ways the kind of “valid existing
rights” that the Forest Service has no warrant to override.

                                                  I.

       Crooked Lake stretches three miles from one end to the other connected by a series of
meandering channels and bays. Nestled within an old growth forest, the lake offers a variety of
outdoor activities for public and private visitors from kayaking to bird watching to hiking along
its shore. Fishing apparently attracts a lot of visitors as well, as the glacier lakes in the area
contain “world-class smallmouth bass fisheries.” Herr v. U.S. Forest Serv., 803 F.3d 809, 813
(6th Cir. 2015). Ninety-five percent of the land surrounding the lake belongs to the federally
protected Sylvania Wilderness, a nature preserve open to the public. The remaining five percent,
 No. 16-2126                Herr, et al. v. United States Forest Serv., et al.             Page 3


positioned in the northern bay, belongs to approximately ten private landowners who own the
property under state law.

        The United States first purchased land in the area in 1966, about 14,000 acres
surrounding the southern portion of Crooked Lake, to supplement the Ottawa National Forest.
In 1987, Congress enacted the Michigan Wilderness Act, 101 Stat. 1274, dedicating these and
other lands to the National Wilderness Preservation System as part of the Sylvania Wilderness,
an area encompassing over 18,000 acres and 36 lakes.

        “Subject to valid existing rights,” the Michigan Wilderness Act directs the Forest Service
to administer this area “in accordance with the provisions of the Wilderness Act of 1964.” Pub.
L. No. 100-184, § 5, 101 Stat. 1274, 1275–76 (1987). The Wilderness Act of 1964 provides that
the Forest Service, a branch of the Department of Agriculture, “shall be responsible for
preserving the wilderness character” of the land.          16 U.S.C. § 1133(b).   It also addresses
motorboat use, explaining that “subject to existing private rights . . . there shall be . . . no use
of . . . motorboats” within any wilderness area. Id. § 1133(c). “[W]here these uses have already
become established,” the Act provides that they “may be permitted to continue subject to such
restrictions as the [Forest Service] deems desirable.” Id. § 1133(d)(1).

        In 1992, the Forest Service amended the management plan for the Ottawa National
Forest. Through what became known as Amendment No. 1, the Service prohibited the use of
sailboats and houseboats on all portions of Crooked Lake within the Sylvania Wilderness. In
1993, several landowners filed a lawsuit challenging the prohibitions, see Stupak-Thrall v.
United States, 843 F. Supp. 327, 328–29 (W.D. Mich. 1994), ominously referred to as Stupak-
Thrall I.

        Stupak-Thrall I ended in a victory for the Forest Service but not for the law of this
Circuit. By an equally divided vote, the en banc court affirmed the district court’s decision to
uphold Amendment No. 1, allowing the sailboat and houseboat restrictions to remain but leaving
no controlling law in its wake. Stupak-Thrall v. United States, 89 F.3d 1269 (6th Cir. 1996)
(en banc). Neither the concurring nor the dissenting opinions at the en banc stage, nor indeed the
vacated panel decision in Stupak-Thrall I, agreed with the district court’s rationale for upholding
 No. 16-2126             Herr, et al. v. United States Forest Serv., et al.               Page 4


these restrictions. Compare Stupak-Thrall, 89 F.3d at 1271 (Moore, J., concurring), with id. at
1290 (Boggs, J., dissenting); Stupak-Thrall v. United States, 70 F.3d 881, 889 (6th Cir. 1995)
(vacated).

        The Forest Service issued another amendment to its plans for Crooked Lake in 1995.
Known as Amendment No. 5, it prohibited the use of “any motor or mechanical device capable
of propelling a watercraft by any means” on the wilderness portion of Crooked Lake. R. 49-4 at
1. This amendment came with an exception: one electric motor no greater than 24 volts in size
or 48 pounds of thrust. Amendment No. 5 also prohibited the operation of any watercraft “in
excess of a ‘slow-no wake speed,’” defined as a maximum of five miles per hour. Id.; R. 50-8 at
23. The Forest Service eventually incorporated these restrictions into the 2006 Forest Plan and a
subsequent 2007 Forest Order, which subjected violators of Amendment No. 5 to criminal
liability.

        Kathy Stupak-Thrall, once again joined by the Gajewskis, filed a second lawsuit. See
Stupak-Thrall v. Glickman, 988 F. Supp. 1055 (W.D. Mich. 1997) (Stupak-Thrall II). The
property owners won this round, securing an injunction prohibiting enforcement of Amendment
No. 5. The district court held that the motorboat restrictions interfered with Thrall’s “‘valid
existing right’ to use gas motor boats on Crooked Lake” and thus fell outside the Forest Service’s
regulatory authority. Id. at 1062. It also held that Amendment No. 5, as applied to Thrall and
the Gajewskis, effected a regulatory taking under the Fifth Amendment. Id. at 1064.

        After this decision, the Forest Service “facilitate[d] the sale of the Gajewski
property . . . to a third-party conservation organization,” The Conservation Fund, which agreed
“to resell the property after encumbering it with a conservation easement” paid for by the Forest
Service. R. 53-44 at 13. Because this development “substantially” reduced motorboat use on
Crooked Lake, the Forest Service voluntarily dismissed its appeal. Id. That left the other piece
of property involved in that case protected by the injunction. To this day, Kathy Stupak-Thrall
(and her guests) remain the only people free to use motorboats, though not sailboats or
houseboats, on all of Crooked Lake.
 No. 16-2126             Herr, et al. v. United States Forest Serv., et al.              Page 5


       When the Amendment No. 5 regulations first went into effect, David and Pamela Herr
were occasional visitors to Crooked Lake. In 2010, they made a commitment to the place,
purchasing two waterfront lots on the lake’s northern bay. The Herrs bought the land with the
intention of using gas-powered motorboats. The seller confirmed these intentions, telling the
Herrs that he had used motorboats in the past “without hindrance by the Forest Service.” R. 4 at
11.

       That turned out to be true for the Herrs as well, at first. The Forest Service not only
allowed such use at the time but facilitated it for them and others. It regularly sold boating
permits to visitors and residents—allowing them access to the lake—and allowed motorboat use
through its public boat landing, located in a federally-owned portion of the northern bay just
outside the wilderness area.

       The Forest Service changed course in 2013. It stopped offering motorboat access at the
landing dock and sent a letter to the Herrs informing them that it planned to “fully enforce” the
existing motorboat restrictions on the federal wilderness portion of the lake, though not the
private portion of the lake.    R. 4-5 at 2.     The Herrs sued the Forest Service under the
Administrative Procedure Act (APA), seeking to enjoin it from enforcing the motorboat
restrictions against them. See 5 U.S.C. § 702. Two environmental-protection organizations and
two property owners (Tim Schmidt and Sylvania Wilderness Cabins) intervened to support the
Forest Service.

       At the Forest Service’s urging, the district court dismissed the case. It held that the
federal courts lacked subject matter jurisdiction over the dispute because the statute of
limitations had run on any APA challenges to the 2007 Forest Order. We reversed. The
limitations period, we explained, amounted to a claims-processing rule and did not create a limit
on our subject matter jurisdiction. The limitations period had not lapsed anyway, we added,
because the Herrs never had an opportunity to challenge the validity of the rule’s application to
them until 2010, when they bought the land, and the Service had not enforced Amendment No. 5
against them until 2013. Herr, 803 F.3d at 813, 819.
 No. 16-2126              Herr, et al. v. United States Forest Serv., et al.                  Page 6


       On remand, the district court ruled for the Forest Service again, this time on the merits.
The court held that the Herrs’ rights to use Crooked Lake did not “exist” at the time of the
Michigan Wilderness Act’s enactment, meaning that the reservation of “valid existing rights” did
not apply to them. Herr v. U.S. Forest Serv., 212 F. Supp. 3d 720, 727–28 (W.D. Mich. 2016).

       Here we are. Again.

                                                  II.

       After nearly a quarter century of litigation over the recreational uses of Crooked Lake,
the parties share some common ground about the resolution of today’s dispute. The parties agree
with, or at least do not dispute, these features of the legal landscape.

       One: The Property Clause of the United States Constitution enables Congress to “make
all needful Rules and Regulations respecting the Territory or other Property belonging to the
United States.” U.S. Const. art. IV, § 3, cl. 2. Though Congress has broad discretion to
determine what regulations it “needs” on its own property, see Kleppe v. New Mexico, 426 U.S.
529, 539–40 (1976), it does not have the same authority over private property, see Camfield v.
United States, 167 U.S. 518 (1897). If private property affects public lands, the government may
regulate the private property to the extent needed to “protect[]” the relevant “federal property.”
Kleppe, 426 U.S. at 538 (discussing Camfield); see Allison H. Eid, The Property Clause and
New Federalism, 75 U. Colo. L. Rev. 1241, 1242 (2004). By way of example, Congress has
authority to prevent an individual from leaving an unmonitored fire near any public “forest,
timber, or [] inflammable material,” even if the fire is on private property. United States v.
Alford, 274 U.S. 264, 266–67 (1927). Congress likewise may prohibit private landowners from
fencing in public property, though the fences remain on the private side of the property line.
Camfield, 167 U.S. at 525.

       Two: The national government exercised its Property Clause power here through the
Michigan Wilderness Act, which granted the Forest Service authority over the Sylvania
Wilderness. This specific grant of authority allowed the Forest Service to regulate the public’s
use of Crooked Lake for boating and related recreation, “subject to valid existing rights.”
 No. 16-2126              Herr, et al. v. United States Forest Serv., et al.                    Page 7


       Three:    State-law riparian and littoral rights represent a form of protected rights
under the Act.     See    Forest   Service    Manual     §   2320.5(16),       http://www.fs.fed.us/cgi-
bin/Directives/get_dirs/fsm?2300; Forest Service Br. 25. Riparian rights give property owners
authority to use rivers that run through or adjacent to their property.             Dyball v. Lennox,
680 N.W.2d 522, 526 (Mich. Ct. App. 2004). Littoral rights give property owners authority to
use lakes on or adjacent to their property. Bott v. Comm’n of Nat. Res. of State of Mich. Dep’t of
Nat. Res., 327 N.W.2d 838, 841 (Mich. 1982). This case concerns littoral rights.

       Under Michigan law, a littoral landowner owns the rights to the bed of any inland lake,
like Crooked Lake, “to the thread or midpoint of the water.” Id. at 841; Lorman v. Benson,
8 Mich. 18, 22 (1860). But littoral landowners also share a right to the reasonable use of the
water’s full surface. Bott, 327 N.W.2d at 842; see 78 Am. Jur. 2d, Waters § 35; Holton v. Ward,
847 N.W.2d 1, 4–6 (Mich. Ct. App. 2014). That means the surface of Crooked Lake, even the
part in the Sylvania Wilderness, does not belong exclusively to the federal government. So too
of the surface of Crooked Lake outside the Sylvania Wilderness; it does not belong exclusively
to the State or the private property owners.         The surface belongs jointly to the federal
government and the private owners of state land on Crooked Lake, both of which maintain a
littoral right to “reasonable use” of the lake’s surface. See Tennant v. Recreation Dev. Corp.,
249 N.W.2d 348, 349 (Mich. Ct. App. 1976); Rice v. Naimish, 155 N.W.2d 370, 372 (Mich. Ct.
App. 1967); see also Yates v. City of Milwaukee, 77 U.S. 497, 499 (1870); Hilt v. Weber,
233 N.W. 159, 168 (Mich. 1930).

       With these background principles in place, we can turn to the question at hand: Does the
Forest Service’s ban on using any motorboats or any other boat that exceeds five miles per hour
violate the “[1] subject to [2] valid existing [3] rights” clause of the Michigan Wilderness Act?
Yes, as an examination of each part of the clause confirms.

       “Subject to.”     “[S]ubject to” means “subordinate” or “subservient.”             Black’s Law
Dictionary 1278 (5th ed. 1979). That means the Forest Service’s regulations must respect the
Herrs’ littoral rights, as the Service’s ability to regulate begins where the Herrs’ “valid existing
rights” end. To the extent the Herrs have the right to use a motorboat under Michigan law on
Crooked Lake, the Forest Service must honor that right—must in short be “subject to” it.
 No. 16-2126              Herr, et al. v. United States Forest Serv., et al.                 Page 8


       “Existing.” But did these littoral rights exist at the time Congress passed the Michigan
Wilderness Act in 1987? Yes. Littoral rights, like most property rights, run with the land.
Thompson v. Enz, 154 N.W.2d 473, 483 (Mich. 1967) (opinion of Kavanagh, J.). The question is
not whether the Herrs had littoral rights on Crooked Lake before Congress passed the Act. It is
whether the prior property owners had those rights before Congress passed the Act. They did.
And they sold those rights along with the rest of the property to the Herrs in 2010. In reaching a
contrary conclusion, the district court erred, as the Forest Service concedes. The Act does not
refer to “valid rights of existing owners”; it refers to “valid existing rights.” Because littoral and
riparian rights run with the land, the Herrs purchased those “existing” rights along with others
when they bought the Crooked Lake property.

       “Valid Rights.” That brings us to the nub of the dispute. As the Forest Service sees it,
littoral and riparian rights permit property owners to use the waters only in reasonable ways, and
a ban on motorboat use and a five-mile-an-hour limit on other boat use amounts to a reasonable
limit for a remote body of water like Crooked Lake. The premise is correct. State law may
indeed impose reasonable limits on littoral and riparian rights.           See Mich. Comp. Laws
§ 324.80108; Miller v. Fabius Twp. Bd., St. Joseph Cty., 114 N.W.2d 205, 208 (Mich. 1962).
But the conclusion is not. When the statute refers to “valid existing rights,” it asks whether the
property owners have such rights under state law, not federal law, and certainly not federal law
as construed by a federal agency. The Herrs plainly have such rights under state law, as ample
Michigan authorities confirm.      Recreational boating, the Michigan courts have repeatedly
indicated, amounts to a reasonable use. See Burt v. Munger, 23 N.W.2d 117, 119–20 (Mich.
1946); Rice, 155 N.W.2d at 372; People v. Hulbert, 91 N.W. 211, 211–12, 218 (Mich. 1902);
Pierce v. Riley, 264 N.W.2d 110, 114 (Mich. Ct. App. 1978); Tennant, 249 N.W.2d at 349.

       Not just these legal authorities, but the facts as well, point in this direction. Landowners
and visitors have used motorboats on Crooked Lake since the 1940s. Stupak-Thrall II, 988 F.
Supp. at 1059. Longstanding prior use is one indicator that a co-riparian (a term used by
Michigan courts to cover littoral and riparian landowners) acts reasonably relative to others.
Dumont v. Kellogg, 29 Mich. 420, 425 (1874).
 No. 16-2126              Herr, et al. v. United States Forest Serv., et al.                Page 9


       No doubt, Michigan could have regulated motorboat use on Crooked Lake during this
time. See Mich. Comp. Laws § 324.80108. And it may even be possible that it could have
banned motorboats, though at the risk of imposing a regulatory taking under the State or Federal
Constitutions. See Difronzo v. Vill. of Port Sanilac, 419 N.W.2d 756, 758 (Mich. Ct. App.
1988). But the key point is that it never did. All agree that Michigan law permits motorboat use
on the northern bay of the lake, outside the Sylvania Wilderness.              The best evidence of
reasonable use under Michigan law is what Michigan law allows on this lake.                 To our
knowledge, no co-riparian has challenged the Herrs’ (or anyone else’s) use of gas-powered
motorboats on this part of Crooked Lake.

       No less significantly, the Forest Service long allowed motorboat use on all of the lake
after it obtained this regulatory authority. And it still does with respect to one property owner.
Until 2013, the Service not only allowed motorboat use, but it also facilitated such use by selling
boating permits and allowing the public to use a loading dock on federal land. It never appealed
the injunction in Stupak-Thrall II, which means that one of the ten property owners on the lake
(and her guests) currently may use motorboats on all of the lake. How odd to allow one property
owner to operate motorboats on the lake, while trying to exclude the other nine. If motorboat use
is objectively unreasonable for one, it is objectively unreasonable for all.

       That does not mean the Herrs have a right to use any size boat at any speed on any part of
the lake, as the district court worried. The Herrs have a right to reasonable use of the lake. That
means a right to travel at reasonable speeds within the lake. But the Forest Service has not
shown that it would be unreasonable under Michigan law to travel on 95% of the lake above a
low-wake-zone speed. If you think otherwise, try being at one end of a three-mile lake with a
five-mile-an-hour speed limit as an unexpected storm sets in.

       A pre-existing use, we suppose, may not invariably amount to a right in all settings. But
Michigan law tells us that boating is typically one stick in the bundle of littoral and riparian
rights. Only if boating on this lake would be unreasonable under state law could we say
otherwise. The long history of pre-existing use confirms that it is not unreasonable to use a gas-
powered motorboat at speeds above five miles per hour on Crooked Lake.
 No. 16-2126              Herr, et al. v. United States Forest Serv., et al.               Page 10


       The Forest Service tries to ground its authority to ban gas-powered motorboats in state
law and the Wilderness Act itself. Neither source delivers. The Forest Service tells us that it can
regulate littoral and riparian rights under the Property Clause to the same extent that state
regulators can regulate them. Maybe; maybe not. But we need not decide. For the Michigan
Wilderness Act does not grant the Forest Service a power coextensive with Congress’ plenary
authority under the Property Clause. It instead delegates a power limited by existing rights—
“subject to valid existing rights.” For that reason, any “police power” the Forest Service may
have must respect pre-existing property rights, not just the limits of state power. Unless or until
the State permissibly says otherwise, littoral property rights include the right to reasonable use of
the water’s surface for recreational motorboating. No matter how reasonable the Forest Service
may think this regulation is, it has no power to nullify the Herrs’ pre-existing right under
Michigan law to use the lake for recreational motorboating.

       That the Wilderness Act contemplates “desirable” regulation of pre-existing motorboat
use ignores the fact that the Michigan Wilderness Act makes the Forest Service’s authority to
enforce the Wilderness Act subject to independent limitations. Though the Michigan Wilderness
Act provides that the Forest Service is to manage this area “in accordance” with the Wilderness
Act, it also provides that such management is “[s]ubject to valid existing rights.” Pub. L. No.
100-184, § 5, 101 Stat. 1274, 1275–76 (1987). That limitation remains controlling.

       All of this does not leave the Forest Service or the Herrs’ neighbors without options.
Fellow riparians may enjoin unreasonable uses under state law through the state and federal
courts. They may petition the State of Michigan to change the boating rules on the surface of
Crooked Lake. Or they may pay the Herrs for an easement on their property, which would limit
motorboat use in the same way the Gajewskis’ property became limited. Even the serenity of
nature sometimes comes at a price.

       For these reasons, we reverse.

       BERNICE B. DONALD, Circuit Judge, dissenting. I agree with the majority that the
Herrs have valid existing rights to which any regulation by the Forest Service must be
subservient. I agree also that the district court erroneously concluded that the Herrs’ rights were
not “existing” because the Herrs purchased their land after the Forest Service passed Amendment
No. 5. Where I disagree, however, is with the majority’s conclusion that a federal agency, in the
same manner as a state, may not impose reasonable restrictions on littoral and riparian rights,
when expressly authorized by Congress to do so.

       First, as the Supreme Court has held, “[t]he general government doubtless has a power
over its own property analogous to the police power of the several states, and the extent to which
it may go in the exercise of such power is measured by the exigencies of the particular case.”
Kleppe v. New Mexico, 426 U.S. 529, 540 (1976) (citing Camfield v. United States, 167 U.S.
518, 525 (1897)). This also “includes the power to regulate in a manner affecting non-federal
property.” Burlison v. United States, 533 F.3d 419, 432 (6th Cir. 2008). As such, the power of
Congress to regulate under the Property Clause “may have some effect on private lands not
otherwise under federal control.” Id. (quoting Kleppe, 426 U.S. at 546). Second, as even the
majority notes, Congress has authorized the Forest Service to regulate the Sylvania Wilderness.
This authority, “subject to valid existing rights,” is coextensive with Congress’ own authority
under the Property Clause when the Forest Service acts to preserve the wilderness character of
the Sylvania Wilderness. It thus follows that the Forest Service possesses a power that is
“analogous to the police power of the several states,” and where the Forest Service does not
exceed the scope of the permissible police power of the state, it may exercise this power.

       It is important then that we first examine the scope of the state’s power to regulate littoral
and riparian rights. In Michigan, “[t]he rights associated with riparian ownership generally
include . . . the right to a reasonable use of the water for general purposes such as boating,
domestic use, etc.” Tennant v. Recreation Dev. Corp., 249 N.W.2d 348, 349 (Mich. Ct. App.
1976). These rights, however, are not without limitation. To protect the public safety, Michigan
 No. 16-2126             Herr, et al. v. United States Forest Serv., et al.              Page 12


permits regulation of the operation of vessels on the waters of the state. Mich. Comp. Laws §
324.80108. To this end, Michigan courts have upheld restrictions from local governments as
they relate to the riparian and littoral rights of citizens within their jurisdictions. See, e.g.,
Square Lake Hills Condominium Ass’n v. Bloomfield Twp., 471 N.W.2d 321, 326 (Mich. 1991)
(permitting Bloomfield Township to regulate boat docking and launching on inland lakes under
the township’s police power); Miller v. Fabius Twp. Bd., 114 N.W.2d 205, 209 (Mich. 1962)
(allowing time regulations on water skiing).

       Recognizing that the state may impose such regulations, the majority nevertheless
concludes that the Forest Service may not regulate Crooked Lake in this manner because
Michigan has not imposed such restrictions itself. But Forest Service’s powers, while restricted,
do not depend on state action. Put another way, state law determines the scope of the Forest
Service’s authority to regulate the surface of Crooked Lake because Congress has placed the
specific constraint of “subject to valid existing rights”; rights that are determined by state law.
But state regulation is not a prerequisite to the Forest Service’s ability to regulate.           The
determining factor, rather, is whether the regulation is a proper exercise of the state’s police
power. And, as previously mentioned, Michigan state law confirms that restrictions on kinds of
vessels and speed of motorboats are permissible.

       The next question is the reasonableness of the restriction. “The reasonableness of an
ordinance . . . depends upon the particular facts of each case. The test for determining whether
an ordinance is reasonable requires us to assess the existence of a rational relationship between
the exercise of police power and the public health, safety, morals, or general welfare in a
particular manner in a given case.” Square Lake Hills, 471 N.W.2d at 324 (citation omitted). As
the district court noted, Amendment No. 5’s restrictions are rationally related to achieving the
Michigan Wilderness Act’s goal of preserving the wilderness character of Sylvania. Also, these
restrictions are certainly reasonable. Amendment No. 5 does not ban the use of all motorboats
on the surface of Crooked Lake; rather, it merely restricts the use of gas-powered motorboats, the
size of the motor, and the speed at which a boat may travel on ninety-five percent of the lake.

       The majority approaches the issue of reasonableness by looking at whether recreational
boating constitutes reasonable use under Michigan law. I agree that the use of gas-powered
 No. 16-2126              Herr, et al. v. United States Forest Serv., et al.              Page 13


motorboats is generally not unreasonable under Michigan law; but this alone is not dispositive of
whether the Forest Service’s ban of such use on Crooked Lake is unreasonable. Neither is the
fact that the Forest Service has previously allowed motorboat use on the entire surface of
Crooked Lake. As the majority notes, a pre-existing use does not always amount to a right.
Initially, what was reasonable in the past is not necessarily reasonable today.          But more
importantly, the Herrs’ right to engage in recreational motorboating under Michigan law, which
does not necessarily equate to a right to use gas-powered motorboats, is not immune from
reasonable future regulation. “Congress chose to ‘grandfather’ private rights in the ‘subject to
valid existing rights’ phrase, but in doing so, it never intended that those rights be ossified
against further regulation.” Stupak-Thrall v. United States, 89 F.3d 1269, 1271 (6th Cir. 1996)
(memo) (Moore, J., concurring in order affirming district court opinion by divided en banc vote).

       Ultimately, I believe that Amendment No. 5 was squarely within the Forest Service’s
authority to enact, and that the restrictions do not infringe on the Herrs’ “valid existing rights.”
For these reasons, I would affirm the district court. I respectfully dissent.
