Although only just one small region of the Adirondacks requires solid sided canister bear protection use by regulation, it is highly recommended for all regions. When I was an instructor training and certifying adult (over 18+) BSA high adventure trek leader guides, it was always an interesting, and often comical exercise for the first night then "leader of the day" being evaluated to organize and effect the best possible bear bag hang. First find the right tree with a good height branch at just the appropriate distance from camp. Not too far, not too close. Then throw a weight tied to the rope over the branch. Missed. oops, missed again. Lost the tied on rock, stick, boot, water bottle, whatever. Got the rope wedged in the crotch of the tree, find a long stick to get it free, Try again. and again, and again. Somebody else tries, with no better luck. Now it is getting dark. Jocks always try an overhand throw until they discover that underhand works best. But a week's worth of food is too heavy to drag over the branch. Try another method. Do you remember the two carabiner pulley method I showed you in class? Let’s try that. Now, can an educated bear see where you tied the rope? Finally, who forgot to put that last candy bar or toothpaste in the bag?
