I don't know about everyone else, but I have read many post-apocalyptic novels, and enjoy those that include prepping. It's my belief that prepping novels are a good way to discuss potential scenarios, and what rational preppers would do in that situation. Obviously, some things are way beyond what rational preppers prepare for, but they can still be a fun, educational read. If you have such a story you've been writing, we'd love to see it!
