a friend of mine who happened to cross the border with the remnants of a roach in his pocket - ended up enduring a full body cavity search, had to pay a significant fine of several hundred US (they wouldnt take Canadian funds - so his friend had to go to a US bank and get the money) and has been banned from the US ever since.
(the incident happened a few years ago just before they instituted the zero-tolerance policy- otherwise his car would have been seized and auctioned off).

in a different case - a canadian truck driver, had his truck seized and held for months - because unbeknowst to him a co-worker left his lunch bag (with an orange in the cab).

my snobbish tone? please excuse me for being ticked off at the inequality of treatment - theres plenty of americans crossing the border that that are outraged theyre not allowed to carry their guns across to canada.

this woman went clear across the entire state, and dont tell me she cant read the signs everywhere that say Vancouver Canada along the way, and her husband is even dumber for having grenade in the car in the first place.
