think about it realistic:
every 'survivalist' and their dog want/have a 'retreat'.
the country is crawling with camo clad nutcases with guns shooting at everything.
do YOU realy think the locals
(wherever area you want to 'bug out' to( will just let you screw up their area with your bunkers w.h.y. and b.s.?
why not stay where you are and IF there is a natural desaster follow the orders of local/state/fed authorities?
getting free food and care packages to booth?
