That's what cracks me up about the people on the Preppers show. Ummmmm hello buddy, now EVERYONE knows you have all this stuff. Where do you think they're gonna show up first?
I have watched most of the episodes of Doomsday Preppers. You may notice that many of the participants in the show are making money from prepping.
One lady was selling pandemic preparedness kits. The guy who shot his thumb off on one episode is selling preparedness supplies. Several of the participants have YouTube channels, and those channels generate advertising revenue for those people.
They are on TV because they want to sell something. Most of them are not really worried about the Earth's poles shifting, the economic collapse of the United States, or whatever. And some people just enjoy prepping as a hobby, and they like meeting other preppers and sharing information. Some of the people are just nuts.
