I think I am lucky in the fact that my mind just doesn't dwell on all these shtf doomsday type scenario. That said I have always liked home grown and canned food much better than store bought, even though it cost more to grow your own, be it vegetables or meat and store it. I tend to think it is better for you, at least I like to think it is, and know for a fact it tastes better.
My opinion is if you do not store the things you need all the time, if something terrible happens, it is too late to start, period. And if you are prepared, there is no such a thing as bugguing out, how would you take your preparations.
Like I said I count myself lucky in the fact that my mind just can't dwell much on anything I can't do about anyway.
