A retreat is not just “a cabin in the mountains.” Rather, it is a well-prepared and defensible redoubt with well-planned logistics. A proper survival retreat is in effect a modern day castle. Be prepared to escalate your defensive posture to match an escalating threat, and in a “worst case” your retreat will be so well defended that looters will most likely give up and find someone less prepared to prey upon. Ideally, a survival retreat is located in a region with the following characteristics:
A long growing season.
Geographic isolation from major population centers.
Sufficient year-round precipitation and surface water.
A diverse economy and agriculture.
Away from interstate freeways and other channelized areas.
Non-intrusive scale of government.
Favorable zoning and inexpensive building permits.
Minimal gun laws.
No major earthquake, hurricane, or tornado risks.
No flooding risk.
No tidal wave risk (at least 200 feet above sea level.)
Minimal forest fire risk.
A lifestyle geared toward self-sufficiency.
Demographics not factionalized either economically or racially.
Plentiful local sources of wood or coal.
No restrictions on keeping livestock.
Not near a prison or large mental institution.
Inexpensive insurance rates (home, auto, health).
Upwind from major nuclear weapons targets.
After digesting the foregoing list and taking it seriously, you should be able to greatly narrow your search for potential retreat regions.
