Have an escape plan

Chances are you were taught this cardinal rule as a fire safety tip in grammar school. Yet even after being chased away from various shelters by a gaggle of zombies, The Walking Dead survivors don't seem to have made any contingency plans, or confirmed a group meet-up place in case of emergency. "If there is a potential for the home base to become unsafe, then it is important to have a ‘back-up home base,'" says Dessinger, though he cautions that this tactic, "is usually only going to work if you are in a reasonably long-term situation. It is important that your back-up spot is a place everyone has been to multiple times so that they can find it easily. There should be no potential obstacles on the way, say a river that could flood and become impassable."
