They sell bear bags EVERYWHERE around here and they're all used with a lanyard for throwing around a tree branch so as to hang the bag at least ten feet off the ground and ten feet away from the trunk. This is supposed to keep a bear out of my food? Ya, right. The last year I've spent in Idaho backcountry I've NEVER had an issue with it. The only time I came remotely close was when we had a pack of coyotes run through our 30+ person camp on the Snake River in Hell's Canyon. Bears, at least around here, are skittish in general-the slightest sound or smell of humans will send them packing. We have millions of square miles of public land, and although we have lots of wildlife, they don't have much experience with human interaction, as they have room to exist away from human society. Whereas a Wisconsin whitetail will sit and stare at you ten yards away, if an Idaho whitetail were to smell you upwind of them they'd be long gone by the time you ever see them. I'd like to see a bear that can't get into a 3 pound plastic bin get into a metal soup can that's burried in a pack. I know they can do it, I'm just saying, I don't care what anyone says, they aren't failsafes.
