Adventist Youth Honors Answer Book/Camping/Food storage
The most important thing you must remember about storing food on a campout is that it should never be stored in a tent where people will sleep. Animals will smell your food, and if it's in your tent, they will find a way in. Instead, store the food outside the tent.
If you have a vehicle available at your campsite, you may store the food inside, but be sure to seal it tightly. A determined bear can get inside a locked vehicle, and if he decides that's what he wants to do, the car will sustain heavy damage. On the other end of the animal spectrum, are mice, which can also enter a locked car - even the trunk. It is therefore important to seal the food tightly so that the aroma does not draw unwanted attention from unwanted visitors.
If you do not have a vehicle or a trailer in which to store your food, you may place it in a bag and suspend it at least 15 feet (4.5 meters) above the ground by tying the bag to a rope and hanging it over a tree branch. Black bears can and do climb trees, so make sure the bag is well out of their reach - away from the trunk, and at least 4 feet (1.2 m) below the branch from which it is suspended.
