A friend of mine and I were talking at work about this sort of thing. He's a self proclaimed gun nut, the revolution is comming type. Im a little more levelheaded. The short version of myside of the conversation was that no matter how much ammo you have (he claims 10k+ for multiple calibers) Food and medical supplies you store, unless you are in a very secure and very deffensible position you could never move all thouse supplies. And that unless you were willing to shoot to kill every man, woman, and child that come to your home looking for help that you would eventually be overrun or burnt out. Thats the short version. Odviously your not going to shoot everyone that walks by but if there were some prolonged crisis situation just how safe do you think you would be in the average home.
