I'm running a post-apocalyptic campaign in GURPS 4E, and the PCs are probably going down the path where their arch villain will be the leader of a survivalist group that has some crazy notions and lots of supplies and ammunition in a more or less centralized compound in a rural area.
I've been trying to research anything in the RPG realm that I can repurpose, with no luck. Do you know of anything? I've since expanded to non-RPG (historical, other fictional settings) for maps, descriptions, layouts, etc.
