Unless you have a completely 4year+ self sufficient bunker built into a remote mountain that completely keeps you out of contact from civilization, you're just wasting your time with prepping.

Keeping a good supply of food and guns is cool for a week or two long scenario, but some of these people that are sacrificing everything in their life so they can live in a little cargo container expecting world wide doom, with a house filled with random prepping shit, pssh, gfto. You're gonna get raped and killed by the mercenaries if you're hording all that material, simple as that. A few broke ass hillbilly's with guns ain't stopping shit if a true world collapse scenario takes place.
