I know for a fact that dogs can't smell gear. I was down there and packed the door panels full. They sent me to the search line and ran a dog all through the car.
I figured that while it may be safer to go on foot and only get a small amount, I would have to make many trips. I would rather play the %'s and get it all in one trip.
One problem: I have heard that whn you bring gear over, you should not bringany packaging that it comes in. Sometimes the same people who sell gear are also into other drugs (ones that dogs can smell). They may have some residue on them. That may explain why dogs sometimes find gear!
