They won't care as they line you up against the wall and ventilate you.
My next door neighbors are both ex-military in their 70's. They have a stockpile of weapons, they have a generator (big) and had contractors over there installing some kind of geothermal bullshit that probably won't do **** in Michigan in January. I don't know if they are "preppers" per se. It just seems as if they include a lot of things within the scope of what they consider to be logically possible that I, and most mammals, consider to be wild-eyed, paranoid delusion. Rural Michigan does not strike me as being likely ground zero for whatever pending doom awaits us.
