A small rural town, with it’s own power supply.
My rural small town is fairly easy to defend, thanks to terrain, not directly on a primary Interstate, plenty of silo storage, and has a small moth-balled hydro plant for power, if need be.
In short, we can be self-sufficient, and defendable, for an extended period, if need be.
The only real problem in a total collapse would be fuel, but with small Natgas wells in the area, and a couple of homemade biodeisel stills, we could make it
That’s what I like about my little village. 150 people, heavily armed, on one side of a lake with a dam. Better yet is the fact that there are other little towns all around with family and social connections for trading and aiding.
