>>What do YOU think are the primary scenarios?<<
You list almost all natural disasters (adjusted for locale). Which I have said over and over and over are a good reason to do gardening, know how to hunt, etc. etc. etc. I know how to plant I know how to hunt. I could survive that way if I had to. But it would be survival as opposed to living.
FWIIW, Tornadic winds would probably mess the garden up, but a tornado might hop past and having a garden would be great to help the neighbors.
>>Socio-economic displacement of urban/suburban free-lance socialists? Possible. Somewhat probable.<<
That statement makes no sense no matter how much I try to parse it. If all the socialists were to leave the cities, then said cities would thrive.
Most Americans, socialist or not, live in cities or suburbs.
'Socio-economic displacement' is food not getting to Wal-Mart on day 5, and the FSL heading toward the suburbs. Did you see the videos of the tramplings recently in a Wal-Mart?
And to your final point, most people in the cities died, back in 1348-1350. Sucks to be urban/suburban.
We're not immune to similar calamities.
And what exactly is wrong with being prepared for the worst possible scenario?
