I always have an escape contingency in mind, but there are only a few situations where I would want to run: toxic spill (which would hopefully be temporary) and a large-scale fire/firestorm.
I have a Ford Ranger with two gas tanks and a camper shell (canopy). The gas would get me about 400 miles. I have friends about 300 miles away, if I had to leave this area.
But for most situations likely to come up around here, escape would not be advisable, or maybe even possible. It's really hard to take off with enough supplies for TEOTWAWKI conditions. And like it or not, there isn't likely to be any place out in the "wilderness" that other people wouldn't have already staked out as theirs. Even if it really is yours. If it's a widespread kind of disaster, you might want to be realistic and not try to depend on local game, because there won't be any. The population density of America has changed considerably from the 1800's.
Ironraven, a friend of mine says she likes to be "mature" in her thinking. When it comes to relatives that I don't like, I run closer to John Steinbeck's way of thinking: "If I were hungry, I would happily hunt anything that runs or crawls or flies, even relatives, and tear them down with my teeth." (John Steinbeck, Travels With Charley)
