You'll need a gun and ammo for protection, a tent, a Gore-Tex sleeping bag, multifaceted work gloves for climbing, bear spray or mace, a single propane stove item, iron skillet, metal cup, utensils, cheesecloth or screen for straining water, candles and matches in a waterproof case and flashlight. Take at least 100 feet of nylon rope, fishing net, hand-cranked radio, rain poncho, heavy trash bags, sewing kit, leather and denim scraps for patching and extra socks.
Don’t forget meds, a compass, an area grid map, a round angle protractor and grease pencil, conversion charts, weather and almanac stuff, a diary, pen and some large paper. You can survive 21 days on water alone. If you can make tree bark tea, you’ve got about 6 months. Pine and maple tree bark are good. Strip bark like eucalyptus and birch are bad. Boil the bark and be sure you have enough nutrients to get by.
