I personally look at #3 but I really think the problem comes with prepping too much to stay, not leave. I hear people always talking about buying this
and buy that ....cases of a little of everything.
Well, last I knew, I could manage about a 100lb pack and that isn't going to be doing anything fancy...quickly...or with grace. The way I'm looking
at this, if we're even fortunate enough to be home if something should happen suddenly ...there are about 100 reasons why any given geographic area
may become untenable. If it isn't sudden, then simply being known for what you have is enough to 'prep' for the possibility of turning your back
and walking away from all of it...if the situation dictates survival that way.
So it always concerns me....How many people who prep and especially among the urban people, have ever even spent a weekend out in the woods with no
running water, electricity, communication devices of ANY kind and nothing but the wind and each others company to pass time by? If things get bad...it
won't be a weekend. It could be much much longer. Homeless is one way to put the way that happens...or worse. Depends on how the future unfolds.
I'd just say that while everyone makes sure there is at LEAST 3-6 weeks of comfortable eating and drinking (Not digging Ramen noodles out from
packing boxes dating to your college days by the 2nd week either

) It's equally important to look outside and at the woods..or desert or wherever
we may be and consider .. "If I have to LIVE in that open natural area for days or weeks and only what I carry.....how?" I know by camping so much
in my youth, it can be done and without Military training ....but it can't very well be learned DURING an emergency that doesn't tolerate mistakes
and grants few second chances.
