This group has a primary concern with maintaining some form of legal system and social cohesion after a breakdown in the technical infrastructure of society. They are interested in works like The Postman by David Brin,[47] Lewis Dartnell's The Knowledge: How to Rebuild Our World from Scratch,[48] or Marcus B. Hatfield's The American Common Law: The Customary Law of the American Nation.[49]

Zombie Squads make up a small portion of the overarching prepper movement—people devoted to learning how to survive any disaster, from a house fire to a zombie attack. The movement, says Huddleston, an anthropologist at Saint Louis University and Southern Illinois University, Edwardsville, has grown “a ton” in recent years. “Because one, people are afraid of things in the world,” he explains. “And two, I think many people have had experiences with different kinds of small-scale or even large-scale disasters, be it Hurricane Katrina or Superstorm Sandy, and they see that there is some practical value in knowing a little bit or having a little bit”—such as knowing how to do first aid or having enough food on hand.

For an hour and 50 minutes, we talk a lot about liberty. The world according to Fletch hinges on the rhetorical question, “Is this going to give me more liberty, or less liberty?” He also assures me that his survivalist group isn’t just white guys running around in the woods with guns. “In my sphere of influence, there are Asians, there are blacks, Native Americans; a person’s race has absolutely nothing to do with anything,” Fletch says.

What’s the bare minimum you need to navigate across land?  For most people, that would be a compass and map.  A basic road map is sufficient to get a rough approximation of the lay of the land.  More detailed relief maps can help plan for elevation and estimate possible water sources but they also take up more room in your pack.  Waterproofed or laminated maps are also extremely helpful.  Lensatic compasses are the most reliable for little money.  If possible, a compass and protractor are also extremely helpful for route planning.  Obviously, not as essential but nonetheless useful.
