good lord some people over pack lol. I have one of those packs with the built in water holder, Filled slightly more than halfway " its fairly big", 2 gonola bars, a sandwitch bag full of trail mix, Knife,compass, small light flashlight " small but its super bright", Lighter, 1 emergency space blanket, And i carry in my head all the survival skills ive learned and remembered from all the mountain man books ive read. You guys know how to keep warm in the mountains with no blanket? If you have a small shovel or the ground is soft, dig down 3 feet, gather some logs to lay across the hole and light a small fire under the logs and sleep on top of the logs. Careful not to build to big of a fire or else you'll really be warm! Another good item to carry in the woods is a small light weight hatchet. Theres really no point in carrying alot of food with you, if you are hunting you are more than likely carrying a gun or bow. And the woods are full of food.
