Preppers, if you don't know, are waiting for the collapse of civil order and (in the words of the Posse Comitatus, a rural Wisconsin anti-government group from the '70s) "buy guns and store food." Don't know if the Posse is still around, but the latest incarnations are. I've noticed shows about them on cable. Now Madison has a few of their own.
I wonder if a certain Second Amendment absolutist is involved.
