I like the solutions they had out west. In Glacier they had a wire strung and at Mt Rainier they had a metal pole with hooks near the top. Of course these were group campsites and probably not applicable to canoe country. Usage seems somewhat down (especially in the Q) and perhaps bear/camper problems will lessen and not increase.

I've had 2 close encounters and it is certainly adrenaline promoting. I can see where it could be a substantial issue if your food gets clipped far from resupply. Education is key. "Bear attacks, causes and avoidance" is the book to read IMO. Very interesting. You will gain an enormous amount of insight into these highly intelligent inhabitants of the north woods.
