This is an effective method for hanging your food out of reach of bears and other critters. Roughly 200 feet away from your camp, ideally look for a tree with a long, strong branch at least 15 feet above the ground with no branches below it. Tie the end of a 60-foot length of thin, strong, tangle-free rope around an oval-shaped rock no larger than a baseball (use a clove hitch, which will easily come undone if the rope gets accidentally tangled up). Now throw the rock over the branch, about 10 feet out from the tree trunk. Once the rope is suspended over the branch, remove the rock and tie on your food bag instead. Haul it up until its about two feet below the branch, then tie off the other end of the rope to the tree trunk.
