Get Your Rocks On
When camping in bear country, take no food into your tent. Hang a pack containing all edibles at least 10 feet off the ground from a rope strung between two trees. Put pebbles in a couple of clean metal cooking utensils, and place them a stone's throw from your tent. Place a pile of throwing-size rocks within reach of your sleeping bag. If a bear awakens you by rattling the utensils, go on the offensive. Shout and throw rocks at the bear. Most bears, finding nothing to eat, will leave if threatened.
