Depends on what happens.
1) You live in a trailer park. Weather man says a bad storm is coming.
2) You live down in a "holler" and a big snow storm is coming.
3) Crop fire in the field next door and the wind is blowing your way.
All of these are "signs" that you might want to temporarily re-locate to a safer place.
Now, if you are asking, "when is it time to become a hermit?" Well, any time is a good time for that. Assuming you'll be self sufficient, and plan to live that way until you die, does timing really matter?
What "sign" would it take and where would you go?
Good question. I have been working on more than one plan depending on how the SHTF happens. On one extreme there is a natural or manmade disaster that wipes out huge population centers and disrupts everything on a national level overnight. On the other extreme there is the long slow slide into the crapper that gets worse every day and one day you must act. Two different plans are required.
There is a third plan that requires learning Mandarin Chinese but I don't like to think about that.
Maybe we should all have 2 or 3 planned scenarios and responses.
Easy now, im on ur side. Just looked into the survival threads for the first time and found it a bit crazy. Seemed like all it was about was crazy occurances that dont seem to likely. Not ruling them out, just unlikely.
