some of them are, i visited a few of the relevant forums, survivalist and ar15.com, to read the great megathreads on bizarre shit they had seen in the woods. some of the members were and a lot of the stories involved all manner of disgruntled, gun toting nutjobs. lone crazies in full camo gear with cached weapons in booby trapped locations, kkk type anti government groups hiding in the forests preparing for the end times, gold prospectors with a dangerously warped view of what rights their plot confers upon them alongside the rabid paranoia. and these were agreed on archetypes, i.e not nearly as rare as one may imagine
anyone with some time to kill should google and search them out. amazing reads
