Whenever I make my way into the States, they always give me the third degree, look through my vehicle, etc. This is at the terminal, not the "tear your fucking vehicle apart because they think you're bringing drugs or meat across the border."
Whenever I make my way into Canada from the States, usually it's, "Where's home?" "Did you buy anything while down there?" "Have a good day." The last time I went through was at like, 2:30am and all they did was ask my name, where I lived, then waved me through. Didn't even want my ID or anything.
