                             I. BACKGROUND
      In 2006, undercover law enforcement officers investigated an MDMA ring
operating around Dallas, Texas. Duong supplied to an undercover agent and
confidential source 1,002, 998, and 522 ecstasy tablets on separate occasions.
Based on these transactions, DEA agents obtained a Title III order allowing
them to monitor Duong’s phone for thirty days. During that time, the agents
overheard calls indicating to them that Duong was going to purchase 15,000
tablets. The agents then witnessed a transaction in Dallas where they believed
the tablets were delivered. Agents intercepted another call indicating that
Duong would be purchasing 5,000 to 10,000 tablets. They observed a meeting
in Arlington where Duong returned to his car with a box. The supplier and co-
defendant, Tho Tieu, later testified that she had delivered ecstasy tablets to
Duong on that occasion. Duong was seen delivering tablets to another co-
defendant the next day who was shortly thereafter arrested in possession of
1,000 tablets.
      Following the return of the original indictment against Duong and others,
officers served an arrest warrant for Tho Tieu at her residence at 711 West
Milton, Arlington, Texas. During a protective sweep of the house, Nguyen was
found in the master bedroom. He was brought to a front room. Nevertheless,
while the officers were searching the house, Nguyen was again found in the
master bedroom next to a baby crib that had a baby carrier in it. Two firearms
were found under the lining of the baby carrier. Various drug paraphernalia
were also found in the master bathroom. Documents bearing Nguyen’s name,
including a plane ticket to Ottawa and Canadian immigration paperwork, were
found in a suitcase in the master bedroom closet. In the garage, officers found
26 kilograms of cocaine and more documents with Nguyen’s name in a Lexus.
Nguyen’s fingerprint was later identified on the tape wrapping one of the
packages of cocaine.

      A superseding indictment and arrest warrant issued to include Nguyen
and the cocaine. The second search of the 711 West Milton residence turned up
732 ecstasy tablets.     Drug paraphernalia were again found in the master
bathroom. A DEA chemist confirmed the presence of cocaine in the washer and
dryer area, on a shelf in the master bedroom closet, on the paraphernalia in the
bathroom, and in two vehicles in the garage. A large amount of cash was found
in a closet.
      A jury convicted Duong and Nguyen of conspiracy to distribute and possess
with intent to distribute MDMA and cocaine. The jury found Duong responsible
for 23,522 tablets and Nguyen responsible for 732 tablets and at least five kilos
of cocaine. Duong was sentenced to 170 months and Nguyen to 188 months of
incarceration. They appeal their convictions and sentences.
                                 II. DISCUSSION
      A.       Duong and Nguyen first contend that there is insufficient evidence
to sustain their convictions. We will not disturb a jury’s verdict if “the evidence,
when reviewed in the light most favorable to the government with all reasonable
inferences and credibility choices made in support of a conviction, allows a
rational fact finder to find every element of the offense beyond a reasonable
doubt.” United States v. Redd, 355 F.3d 866, 872 (5th Cir. 2003) (quoting United
States v. Harris, 293 F.3d 863, 869 (5th Cir. 2002)).
      Duong argues that there is insufficient evidence to establish that he
participated in transactions involving 23,522 tablets. The Government relied on
two wire intercepts between Duong and a co-defendant as evidence that Duong
picked up 15,000 tablets in one transaction. The tablets were not seized. In the
first intercept, Duong is told to “get 15 from Nam’s side. . .three different kinds
. . .five, five” and later “it’s five, five, five, five.” The extra “five” was described
as a misnomer. For a separate transaction, the Government estimated that
Duong traded 5,000 to 10,000 tablets based on an intercept in which Duong

                                           3
                                  No. 07-40990

asked whether the number of tablets is “five or ten” and Tieu responded, “That
much or less.” These tablets were also not seized.
      The jury heard extensive testimony from DEA Special Agent Keith Olson
who believed that the intercepted conversations were referring to 15,000 tablets
for the first transaction and 5,000 to 10,000 for the second transaction. Although
not qualified as an expert, Special Agent Olson’s extensive participation in the
investigation “allowed him to form opinions concerning the meaning of certain
code words used in this drug ring based on his personal perceptions.” United
States v. Miranda, 248 F.3d 434, 441 (5th Cir. 2001).
      Duong offers alternative plausible explanations for the intercepted
conversations, which could have led a reasonable jury to believe that less ecstasy
was involved in these transactions. Regardless, this court reviews the jury’s
verdict only to determine whether it was reasonable, not whether it was correct.
United States v. Williams, 264 F.3d 561, 576 (5th Cir. 2001). Based on Special
Agent Olson’s testimony, the intercepts, and the evidence of 3,522 tablets
exchanged in other deals, a reasonable jury could find that Duong was
responsible for 23,522 ecstasy tablets.
      Nguyen contends that the evidence presented by the Government was
insufficient to allow a reasonable jury to find that he was part of the conspiracy.
To convict Nguyen, the Government had to prove that a conspiracy existed, that
Nguyen knew about it, and that he joined and voluntarily participated in it.
United States v. Garcia, 86 F.3d 394, 398 (5th Cir. 1996).        Circumstantial
evidence of these elements suffices. Nguyen concedes that he was staying at
Tieu’s house but argues that he was not involved in the conspiracy and that “the
government may not prove a conspiracy merely by presenting evidence placing
the defendant in a climate of activity that reeks of something foul.” United
States v. Maltos, 985 F.2d 743, 746 (5th Cir. 1992) (internal quotation omitted).



                                          4

      Nguyen had been staying at the 711 West Milton residence in Arlington,
Texas, for at least a week before the first search of the home and continued to
reside there until the second search occurred.      During both searches, drug
paraphernalia were found in the master bedroom and bathroom that he
occupied. Nguyen’s confirmed fingerprint was found on the tape that wrapped
one of 26 kilograms of cocaine found in the Lexus that he and Tieu both drove.
Tieu testified that Nam Ngo, another co-defendant, introduced her to Nguyen
and that she overheard Nguyen and Nam Ngo discussing the trading of powder
cocaine for MDMA tablets in Canada. She also testified that the 26 kilograms
of cocaine found in the back of the vehicle in the garage might have belonged to
both Nam Ngo and Nguyen. Although mere presence and association with co-
conspirators are insufficient to support a conviction for conspiracy, see United
States v. Sacerio, 952 F.2d 860, 865 (5th Cir. 1992), there is certainly more than
mere presence in this case. A reasonable jury could rely on Tieu’s testimony and
the significant circumstantial evidence to find that Nguyen was a member of the
conspiracy.
      B.      Nguyen next argues that the district court erred when it allowed the
Government to introduce evidence of Nguyen’s trip to Canada, testimony on the
practice of drug trafficking between the United States and Canada, and evidence
from the search of the residence at 711 West Milton. Evidentiary rulings are
generally reviewed for abuse of discretion and are subject to harmless error
review when properly objected to in the district court. United States v. Williams,
957 F.2d 1238, 1240-41 (5th Cir. 1992). If error is not properly preserved, this
court reviews such rulings only for plain error. United States v. Jimenez, 256
F.3d 330, 340 (5th Cir. 2001).
      The Government introduced a Canadian flight itinerary in Nguyen’s name
and immigration paperwork for Canadian travel bearing Nguyen’s name.
Nguyen objected to both exhibits. He argues that the evidence was unfairly

                                         5
                                  No. 07-40990

prejudicial and that the district court erred under F ED. R. E VID. 403 because it
allowed “concededly relevant evidence to lure the factfinder into declaring guilt
on a ground different from proof specific to the offense charged.” Old Chief v.
United States, 519 U.S. 172, 180 (1997). Proof of travel to Canada, however, is
not prejudicial on its own. Evidence of this trip would not lure the jury into
finding Nguyen guilty out of a prejudice against those who travel to Canada.
If the evidence is prejudicial, it is prejudicial—as in most damaging—because of
its relevance to the case.
      The Government also solicited testimony from Special Agent Olson about
the recent pattern in trafficking of trading powder cocaine from the United
States for ecstasy pills in Canada. Nguyen did not object to the introduction of
this testimony at trial, requiring our review of the admission of the testimony
for plain error. See United States v. Jimenez, 256 F.3d 330, 340 (5th Cir. 2001).
This court has held that “an experienced narcotics agent may testify about the
significance of certain conduct or methods of operation unique to the drug
distribution business.” United States v. Washington, 44 F.3d 1271, 1283 (5th
Cir. 1995). While a timely objection to this testimony might have resulted in the
exclusion of some of Agent Olson’s testimony, we cannot say that plain error
occurred. In any event, such error would be harmless in light of the totality of
evidence against Nguyen.
      Nguyen also claims that the district court erroneously admitted into
evidence two firearms and drug paraphernalia confiscated during the search of
the 711 West Milton residence.       He argues that the evidence was highly
prejudicial and not probative because it constituted inadmissible evidence of
extraneous misconduct. If this were evidence of extrinsic misconduct, it would
have to be relevant to an issue other than the defendant’s character and would
have to possess probative value that is not outweighed by its possible prejudice.

                                  No. 07-40990

See United States v. Bentley-Smith, 2 F.3d 1368, 1377 & n.11 (5th Cir. 1993).
Nguyen’s premise is, however, incorrect.
      Firearms are considered “tools of the trade” in drug trafficking offenses
and are relevant intrinsic proof of an ongoing conspiracy. See United States v.
Garza, 118 F.3d 278, 285 (5th Cir. 1997). This court recently reiterated this
conclusion in a drug trafficking case where the amount and street value of the
drugs made the possession of firearms foreseeable.          See United States v.
Cisneros-Gutierrez, 517 F.3d 751, 766 (5th Cir. 2008). In this case, Nguyen was
standing near the baby crib where the guns were secreted, and Tieu testified
that Nguyen told her that a friend had given him the guns.
      This court has also held that “[e]vidence of [the defendant’s] personal use
of cocaine . . . was not extrinsic evidence; it was ‘inextricably intertwined with
the evidence used to prove the crime charged, [and] is admissible so that the jury
may evaluate all of the circumstances under which the defendant acted.’” United
States v. Maceo, 947 F.2d 1191, 1199 (5th Cir. 1991) (quoting United States v.
Randall, 887 F.2d 1262, 1268 (5th Cir. 1989)). Thus, both the firearms and drug
paraphernalia are admissible, intrinsic evidence supporting Nguyen’s knowledge
of and participation in the conspiracy.
      C.    Duong contends that the Government failed to establish that venue
was proper in the Eastern District of Texas. This court reviews a finding of
proper venue for abuse of discretion. United States v. Lipscomb, 299 F.3d 303,
338 (5th Cir. 2002).    Duong concedes that a drug transaction occurred in
Lewisville, Texas, which is located in the Eastern District of Texas. Venue in a
criminal conspiracy case is “proper in any district where the agreement was
formed or an overt act occurred . . . even where it permits trial against
defendants in a district they never even set foot in prior to trial.” United States
v. Caldwell, 16 F.3d 623, 624 (5th Cir. 1994) (internal citations omitted). This
contention is meritless.

      D.     Finally, Nguyen and Duong appeal their sentences. This court
reviews the district court’s factual findings pertaining to a sentence for clear
error. See United States v. Cooper, 274 F.3d 230, 245 (5th Cir. 2001).
      Duong argues that the district court used an inflated average weight of
MDMA tablets to determine his sentence under the sentencing guidelines. The
Guidelines   set   the   typical   weight   of   an   MDMA    tablet   at   250mg.
U.S.S.G. § 2D1.1, n.11. In this case, the Government weighed 3,553 of the
23,522 tablets and found the average weight to be 263 mg. The district court
used this average instead of the typical weight for sentencing purposes.
      Duong urges that weighing only fifteen percent of the tablets does not
yield sufficiently reliable evidence to support the district court’s finding under
U.S.S.G. § 2D1.1, n.11. The Note, however, requires a court to deviate from the
table of typical weights if it finds more reliable evidence. Id. (“Do not use this
table if any more reliable estimate of the total weight is available from case-
specific information.”) Duong also cites United States v. Sims, 975 F.2d 1225,
1243 (6th Cir. 1992) for the proposition that the court should err on the side of
caution when estimating the quantity of drugs. Sims holds that “when choosing
between a number of plausible estimates of drug quantity, none of which is more
likely than not the correct quantity, a court must err on the side of caution.” Id.
Sims would not apply where, as here, there are not two equably plausible
estimates, but one estimate based on case-specific weights and the other merely
a hypothetical typical weight provided by the Guidelines. Finally, we reiterate
that a “district court may consider estimates of the quantity of drugs for
sentencing purposes . . . [and] may extrapolate the quantity from ‘any
information that has sufficient indicia of reliability to support its probable
accuracy, including a probation officer’s testimony, a policeman’s approximation
of unrecovered drugs, and even hearsay.’” United States v. Valdez, 453 F.3d 252,
267 (5th Cir. 2006) (quoting United States v. Alford, 142 F.3d 825, 832 (5th Cir.

                                        8
                                  No. 07-40990

1998) (internal quotations omitted)). The district court did not err in calculating
Duong’s sentence.
      Nguyen contests the two-level sentence enhancement applied for his
possession of a dangerous weapon under U.S.S.G § 2D1.1(b)(1). To apply this
enhancement, the district court must find by a preponderance of the evidence
that “the defendant personally possessed the weapon” and that “a temporal and
spatial relation existed between the weapon, the drug trafficking activity, and
the defendant.” United States v. Hooten, 942 F.2d 878, 882 (5th Cir. 1991). The
dispositive factor is “accessibility of the weapon to the defendant” unless “it is
clearly improbable that the weapon was connected to the offense.” United States
v. Rodriguez, 62 F.3d 723, 724-25 (5th Cir. 1995). Tieu’s testimony, Nguyen’s
presence next to the crib when the police found him, and the firearms’ proximity
to the drug paraphernalia allowed the court to infer that the guns were
connected to Nguyen’s drug trafficking. At a minimum, the finding was not
clearly erroneous.
                              III. CONCLUSION
      For the foregoing reasons, the judgments and sentences imposed by the
district court are AFFIRMED.
