As for the firearms and personal defense, about all I can say is if you have a gun, be prepared to use it and don't be afraid of it. If you don't think you could aim it at another person, you'd better get into shape, because you almost certainly will have a fight on your hands. Better to have a reliable handgun with a laser sight ("point and shoot") than get shot, choked, stabbed, etc from close-contact struggle.
Oh I agree on the use and feeding of firearms. I just think the show is a joke exploiting people to make them look bad.
Its amazing how many preppers ignore one of the most important items, that of being in shape.
I have started canning butter in jars. It isn't difficult and tastes better. When there is a good sale, I take advantage.
