Otherwise, it's better to be smart, and mobile. 2 years' worth of dried food and toilet paper doesn't do you much good if it's underwater.
That's just my opinion, and you're absolutely welcome to agree or disagree. I don't mock people for being prepared, I only mock those (and there are plenty on FR) who feverently wish and hope for the end of the world, just so that they can use their caches of stuff. The "Come and Get Some" Armchair Warriors who "have plenty of lead, and aren't afraid to use it". Whatever. Better to be quiet, smart and mobile, than to make a target out of yourself by loudly beating your chest.
Personally, I buy TP (and other stuff) in big bulk packs because I'm cheap. :-) I make sure that - especially during hurricane season - there's plenty of bottled water, meds, and so on in the house. At any one point in time, there's probably a month or so of food in the house (again, more during ice storm / hurricane season). And so on. Nothing that I can't fit, quickly and easily, in the truck if things go south and I need to bug out. Does that make me a prepper? Or an anti-prepper? Who knows, but it works for me.
Words of wisdom.
