Anytime I cross at Port, Huron Michigan, I always get sent for X-RAY. It's not even like I ever don't get x-ray. I just find it annoying especially when the line is 10 trucks long.
Crossing into Detroit, never had any problems and have never been X-RAYED.
I just find it odd, I don't think it's "random" if I get sent there everytime.
Anyone else have similar experiences at different points of entry? The Sarnia side is pretty bad in terms of guards having a stick up their ### from my experiences.
