Watching the Science channel "Outrageous Acts of Science" (lets not get into the lack of any real science) where they showed video of an Interagency Grizzly Bear Committee ( http://igbconline.org/ ) facility which uses rescued live grizzly bears to test how well things like coolers, trash cans and bear canisters resist bears attempts to open them.
I had no idea there was such a thing and apparently there are actually two organization who do this, both of which maintain lists of what they've test and rated.
