We're probably more prepared for your general SHTF scenario than most. We've got plans, bug out bags with enough stuff to last for a week or so if we have to get out in a hurry. 3 months worth of food. Enough guns and ammo to arm the neighbors against anything short of a large scale organized assault. Karen is a little paranoid of storms so we'll probably be putting a 4x8 above ground steel storm shelter in the garage latter this year.
Nukes pose a problem though as we're just a couple of miles from what's probably a primary target for the Russians.
I've read that the Russian's like 400 kt yield weapons. If we were home, and they dropped one on the MDA HQ we'd be out of the 5 psi over pressure zone but well withing the 10 k/cal thermal zone.
That's 3rd degree burns from the thermal. I don't know if it would set the building on fire though. Plus just because we're out of the 5 psi over pressure zone doesn't mean there still would be enough pressure to collapse the building. So even if we were in the storm shelter and it saved us from the blast, chances are the building could collapse around us and burn while we sat in a big fucking oven.
