Here is a tip for people preparing for some future disaster, of the survivalist type:
Do not turn yourself into a target. If you stockpile useful stuff, then when supplies run out for other people guess where they will look next? You! Then you will need all the guns and ammo you can lay your hands on.
Think of a siege, of the western films with guys in their wooden house, shooting out into the wild at the surrounding attackers. Pretty desperate stuff! Is that how you want to live?
For ideas on how to really survive, I teach eco-survival, wild food foraging, inconspicuous living and how to avoid the ecological collapse that will precipitate the violence and competition.
It is fun too, here and now, which seems a good thing :)
