Relax folks. To properly prepare for all contingencies, You'd have to kidnap and hold a surgeon, pharmacist, priest, shrink, general contractor, farmer, and a bevy of hot teenage hookers. When the SHTF, it really won't matter-any good soldier will tell you no battle plan survives first contact with the enemy. Aside from laying in a good supply of food, water, medicine and ammo, there's really nothing you can do. Bug-out is a fantasy and insane on its face. No matter where you go, you're toast when the pitchforks-and-torches crowd shows up. Just watch reruns of "The Omega Man," and "No Blade Of Grass."
I live in a gated, fully fenced retirement community. We're an island of 1950s sanity in a city and world gone mad. Nobody can remember the last time a crime was ever committed within our park, and people are comfortable leaving cars and homes unlocked. It would take me half an hour to find my house keys. They're somewhere in this desk. I think. If the SHTF, I'm sure we'd all happily mobilize our little community of around 400 families to guard and secure our little refuge until things either settle down and order is restored, or civilization is a total loss and then who cares anyway. I have no desire to survive the collapse of my country just to relive the Dark Ages.
If you project even a hint of preparedness, you might as well paint large targets on yourself and family for the convenience of the great unwashed that is unprepared. Unless your plans include being part of a large group of similarly-situated people with pooled resources and a common interest in riding out the crisis, you might as well not plan at all. There's safety in numbers, not in going it alone.
