But if you are among the swelling class of weekend paranoiacs of affluent means who are starting to mull fantasies of urban escape following the endless headlines about disasters, both natural and manufactured, you may be starting to see a different image in your mind when think “survivalist.” You may no longer see the wild-eyed cave dweller in camouflage fatigues, hoarding canned goods. You may even see one in the mirror.
When searching for immediate, short-term shelter, look for trees (especially fallen trees), rocky overhangs, and caves. Trees are an obvious source of shelter and have many useful parts for building shelter including the trunk – which can be used as a support, the branches – which can be used as framework, and foliage – which can be used as insulating material.
