Readers digest back to basics teaches basic survival skills. Useful knowledge for preppers or anyone interested in living off the land. I purchased this when I was a lot younger and lived back in the pineywoods in east Texas. I am living in town in central texas now and I am too old to care if I survive a holocaust,so I am passing this on to someone else. It has been gently read by only me, so there is no writing, folds or rips. From a smoke free home with pets.
