I've hiked around Mr and Mrs Griz all my life, I've most often hung food and in recent years have used (and had beat up/slobbered on) an ursack with them (well, I actually don't know it was a grizzly, but probably). I'm not too worried about wanting a canister for grizzlies. It's only for those black bears you folks have down south where I have to have it.

Only thing I've ever lost food to is rodents. they're insidious.

The ursack or a proper hang and some brains is all I need up here. (Other than in polar bear turf).
