I don't know if this is a possibility, but what about a forum based around the Survivalist mentality. I.E. Post nuclear war, alien invasion, dawn of
the dead, anything you can think of. Unless of course that would fit into another category that's already established.
I would imagine stuff like that naturally clutters up in NWO, Secret Societies, Military, and BTS. Can't imagine there's enough that it would
warrant it's own forum (No offense, it's just a bit too specialized. ATS is confusing to navigate as it is).
