I've only crossed once, and the guard going into Canada wanted to look inside. Upon opening the door and going in, he said, "That's pretty cool for camping, eh!" He did a 20 second look around, pulled back the covers on the bed, opened the cooler, unzipped one of the cupboards, and asked the usual questions about guns, ammo, tobacco, etc. "That's a lot of fishin' poles, eh!"
Coming back into my own country for which my father, friends, and relatives have fought for, the customs agents are their usual @sshole selves.

I've never met a US customs agent who could smile, crack a joke, laugh, or act like he's even human--on land or by air. Just pisses me off. And really pisses me off when I think I pay their salaries and benefits.
