That's why when I found a copy of John and Geri McPherson's book Primitive Wilderness Living and Survival Skills: Naked into the Wilderness at a flea market, I couldn't resist picking it up. First, it's important to mention that if you're looking for a funny how-to, this is far from it. The McPhersons have put together this book with the intent of sharing the true essence of basic human survival, sans any type of modern convenience or intervention.
While it's not the type of book I'd read cover to cover for entertainment, it is a compelling, and quite fascinating, resource outlining everything you need to know to truly survive the wilderness. It's amazing how thorough and detailed every section is, from how to tan hides with brains to baking over a campfire. You'll learn how to trap animals and what insects you can count on to nourish you.
If you're into survival guides, you have to get Primitive Wilderness Living and Survival Skills. It's an outstanding resource among the genre and really gives you an appreciation for how simple and complex living without can truly be.
