We have been "tent campers" for over thirty years. (Archaeological "digs" are seldom in civilized and easily-accessible locations...) So, when the need arises, we just shift into "camping mode".
I recall one hurricane in MA: when the electricity went off, my wife just lifted her pot of chowder-in-progress off the electric range and onto the Coleman stove. While others were panicking and depressed, we just enjoyed a comfortable "indoors campout". In this (nuke) scenario, we would have done the same -- but in the basement...
I know! It amazes me how many people have absolutely NO survival skills. We've lost that in ONE short generation!
Granted, Army training helps, and knowing how to hunt and fish helps (before everything is blanketed in nuclear waste) and not minding getting dirt under your fingernails helps, too. A garden helps, and having laying hens helps, though I don't really want to eat Green Eggs with or without the Ham, thank you, LOL!
We live in the boonies and I can't begin to tell you how many times our power has gone out at inopportune times. A generator is next on the list; we have a wind up radio and shake-able flashlights, flares, candles, gas grill and Coleman everything.
So, if any Freepers are in southern Wisconsin when the balloon goes us, drag your sorry butts on over here and we'll get through this together. ;)
