I was raised a "prepper" if you want to call it that,,My parents and grandparents lived through the depression,and knew the value of storing and conserving food/supplies. The show on Nat geo,is not bad in my opinion,but some of the people go a little to far with some of it,,,like 75-100 guns? I like guns to,but in a bad situation you risk getting them taken from you by the thugs.The biggest fault I see with most of them is not enough water.If you can drill a well,thats the ticket! Those old hand pitcher pumps still work. I do think its good for everyone to have a cache put away.
