Survival Smokers: If the situation and time allow, you should preserve the extra meat for later use. In warmer climates, you will need to use a drying or smoking process to preserve it. One night of heavy smoking will make meat edible for about 1 week. Two nights will make it remain edible for 2 to 4 weeks. To prepare meat for drying or smoking, cut it with the grain in one-quater inch strips.
