I ALWAYS CHOOSE THE WRONG LINE!
Friday night at 11pm the line was not that long, and since I usually get stuck for an hour in the far left lane, I chose the middle lane. Wrong! While the left and right moved at record pace, I sat and sat and sat in the middle lane. Ugh! I counted 35 cars total passed me before I got to the border agent.
With that said, I never bring anything to declare, the agents are usually very nice, and it's never been a bad experience. Getting into Canada is strict, going into the States is more relaxed. The agents ask the same questions, but never ask you to pay customs for the beer you bring over! 'MERICA!
Anyway, it's a border. What else can you really say?
