prepping is bullshit...the minute the shit hits the fan people will loot your supply...you can own as much guns as you want, one bottle of gasoline and a burning rug will make you run out of your burning shelter and you will be picked off like its nothing...if anybody and I mean ANYBODY knows about your stash the minute the hunger hits you will be visited...prepare to die or hand over your food...
i really know about this stuff I was in 2 wars....
If you want my advice on how to prepare for doomsday:
buy cigarettes, they keep for a long time, when the shit hits the fan food will run out quick anyway, you will be forced to pay like 10$ for an egg or 20$ for a gallon of milk, but cigarettes will appreciate in value accordingly...never underestimate the value of cigarettes to tobacco addicts

...you would be amazed at how far a carton box of maleys will last you if traded for food...do not trade food!!!!!! people will think you have a supply!!! never make them think this!!!!!! cigs are a whole different story...nobody will think you have a cig stash....
forget stashing money and gold, go for cigs and medicine...also a clean water supply/filter and a power generator that runs on diesel is a very very wise move...
also screw shelters, you do not want to be trapped inside a burning shelter...go for the woods...
