•Maintaining contact with others, in the wake of a disaster, will help hold at bay despair. "Ham" radio may be your most likely means of maintaining contact when phone lines and the web fall into disrepair.

•A good bow, and perhaps surprisingly, an air rifle, represent weapons that can be maintained operable with primitive tools and materials.
