Quoted:
The first, unspoken, but most important "Case" is, "In case I survive the initial calamity." We don't like to think about it, but if when the SHTF we draw the unlucky card, well then we'll no longer have any earthly worries, and the question of "Did I store the right ratio of bullets to beans?" just won't matter.
^^^^This. The few folks at work that I have unsuccessfully converted still give me crap saying "If we all die, what's the point?", my response is "What if I live?" My primary reasons for prepping are upstairs asleep in their beds right now. No matter what life throws at me, at least I can still feed my kids, and that's all that really matters.
For a situation like this, I guess it's really about options and not having your eggs all in one basket. I'm fortunate enough to have family with large tracts of land in various locations across the country. I have a modest amount of preps securely stored at each location, enough to get by, but not enough to fret over if I can't ever use it. I figure that way, as long as I can travel, I might have a chance of reaching one of my chosen spots.
