One Rex84 camp is way to close in proximity to my house for comfort.
I drive past the supposed location of one camp in Carrollton, Texas every day on my way home from work. It's identified as a water treatment plant and that's exactly what it is - no "camp" features at all. No barracks, no prison yard fence with concertina wire, nothing. Heck, there's not even a gate at the entrance.
I'll be keeping an eye on it, though. I'm sure the proprietor at my local gunshop (a Class III firearms dealer, no less) will find this information interesting... his shop is two blocks away from the camp location. Not that he needs any help drumming up business these days...
