Nah, doubt it. Preppers are a weird bunch. Nice people, but when they get onto the prepper stuff you wonder about their mental health. Though there's various range of preppers. Most common I've come across are people who live in areas where natural disaster strikes often and it makes sense to be prepared. Others think a nuclear blast will occur.
That said, preppers are also some of the best people to ask for nature advice because they're usually the type of person who knows how to live off the land, off the grid and are very capable in most environments they've honed their skills in.
