Bowron Lakes (Central B.C. grizzly country) has a sheet metal bear-proof locker at each campsite for you to put your food pack in - seems to work and (IMO) doesn't detract from the wilderness canoeing experience at all. (Once the campsite and outhouse are there, a dark green box in the bushes doesn't make any difference).

I think the takeaway from this vid is that once a bear learns that nylon packs have food in them, hanging - even really diligent hanging - will only be a minor deterrent. Barrels seemed to work in this case, but I wonder if the outcome would have been the same if the bear had learned that blue barrels have food in them too.

Keeping your camp clean and your food as odour-free as possible seems to be basic wilderness common sense.
