Those are some of the reasons I would want to be at home when "the big one" (earthquake) hits Kalifornia.
Small town (1200 people), 120 miles from LA, close to USMC base Twentynine Palms, 10+ miles to nearest town across open desert, otherwise only one paved road runs through.
There is a steep, narrow, winding canyon between us and the nearest interstate.
If necessary, it wouldn't be too difficult to close down that road.
My place sits 1 mile back from the paved through road.
Beginning 2 neighbors to the north, it is 17 miles across open desert BLM land to the nearest private property.
A tough bugout, but a nice barrier.
Within 1/2 mile of me are:
at least 20 backhoes, tractors, etc. useful for clearing debris or erecting barricades - with associated fuel tanks,
at least 100 off road vehicles,
about 25 riding horses,
at least 20 private wells,
4 county wells,
LOTS of neighbors with backup power, radio communications, weapons & the will to fend off invaders.
A small group of us have made some plans for holding out in our neighborhood, and watching out for each other.
The biggest problem is that it is in Kalifornia.
No attempt to hijack the thread, just some of the things I've thought on the past decade.
Those are some of the things I intend to have around me where I go from now on out.
We are all on 5 acre lots here - close enough for shouting to work as communication with nearest neighbors, rapid response, overlapping fields of fire, etc.
I probably wouldn't recommend any more space between neighbors in a SHTF or TEOTWAKI scenario - just my 0.02 worth.
Take care,
