Just got done watching Nat Geo's Doomsday preppers, pretty interesting, although probabbly extreme.
So for anyone with an interest here is a FREE pdf manual on preparednes, compiled by the LDS.
http://dl.dropbox.com/u/20859980/LDS%20Preparedness%20Manual.pdf Very Comprehensive Manual, and good checklists throughout, these people are Professionals at prepping, a wealth of knowledge here.
I don't aspire to ever be as prepared as either of the above peoples, but I can sustain my family of five for a month if need be. Just for the record I am not waiting for the end of the world, however I am wary of our JIT infrastructure.
The great thing is, on my scale of things, it is not a waste of money or time, as everything can and is used/rotated perpetually. Nope no grain mills, or wind turbines here.
