The crackers are about the same calories (each) as a slice of bread - 100. Shelf life is 25 or more years.

Big tubs of food. wow.
I hear some Wal-Marts stock this kind of stuff. A few of these and some water flters, kool-aid, tea bags, honey (never ever spoils) etc and someone could survive a disaster for months.
as long as they can defend it.
I guess if I had the cash and a basement I would make the whole thing a Faraday cage (heh) stock it full of years worth of food, generators, short wave radio, satellite radio, water filters/tablets, first aid stuff, extra boots and gear. One of those “make soda at home” things with tons of syrup... heh...
And make it where no one even knew how to get to the basement.
OK... that is probably the Valhalla of Preppers I guess
