The first campsite we stopped at near Lake Louis in the Canadian Rockies had an electrified fence around it to keep the bears out. I'm a bit skeptical about just how secure was with periodic gates you simply had to pull on to open, but none got it while we were there. I liked the graphic though, and may do something with it at some point. Maybe toss it(or a portion of it) on a t-shirt? We'll see.
