It’s one you can get to with minimal time and effort from where you are, with a support network already in place, family, friends, likeminded acquaintances. It’s one that has minimal threats and maximal potential to support your needs for the duration. Food and the ability to grow more, water, fuel whether that’s firewood or something else. A mild temperate climate and good soil would certainly help, but that’s not near enough for many.
Good comment - I used to have a support network in such a location, but that ship done sailed.
So I have to look outward.
