I've seen the show and have been impressed with the intensity of these folks.
One guy did not want to be dependent on ammunition so he is prepping with tomahawks. Water, food, there's nothing these folks are not prepared for. Wow!
Omg I loooooooove this show! How nutty some ppl are.
Some may be valid but I recall one episode a guy in NYC was worried about some volcano. He had some hazmat suit and practiced walking to his storage shed one night in the whole getup. I bet he freaked some ppl out walking along the streets in that when it was dark out.
