The district court found that Trooper Dean’s testimony was credible and uncontradicted. See Williams, 271 F.3d at 1269 (relying on officer’s testimony that defendant’s “extreme nervousness did not dissipate throughout the entire stop”). 2.“Bizarre” travel plans “We have noted numerous times that implausible travel plans can form a basis for reasonable suspicion.” Contreras, 506 F.3d at 1036; see also United States v. Mendez, 118 F.3d 1426, 1431 (10th Cir.1997) (<HOLDING>); United States v. McRae, 81 F.3d 1528, 1535
