Doomsday preppers: brilliant survivalists or paranoid nut bags?

I've been thinking about this for years and have decided that once I've caught up on some bigger outstanding bills that I'm going to stock up on ammo, food, water, and some other supplies.

I already have a good amount of stuff in my VW bus (Westfalia), but probably only a few days worth which is not enough for much other than a camping trip...

I've mentioned this before, but I still would like to save up and buy all the equipment and supplies needed to do my own reloading.

So I'm not well prepared, but at least I'm not like most people who have nothing at all.

Plus the bus is an awesome bugout vehicle.
