That's not unusual to find around here (living in Virginia Beach, Virginia now. Navy and ex-military all over the place). If you head a little further south into the Carolinas, you'll run into some more of the military collectors along with the doomsday preppers.
What I found in a WalMart parking lot was some damn lady who was hung over in her 50's, looked like a scrawny heroin addict, tried to come on to me offering sex for money, and showed me a medical tube sticking out of her stomach.
That's in addition to the usual drug addicts, con-men and riff raff I've encountered at Wal Marts. I've been a bit reluctant to go to them since.
