Rigs,
It's actually a case of AWARENESS that you develop after being in MAXIMUM hypervigilance(sp) for any length of time. Our law enforcement in inner cities, Border Patrol, and of course our military personnel who've been exposed to combat situations. This awareness should become a constant part of every day life nowadays for folks within cities, and especially the women folk. I live in a little old farming town 30 miles outside Boise and it's VERY easy to let one's self become complacent so that when I pop over the hill into Boise city I catch myself with my guard down. Boise has big city issues as it 's situated on I-84 which is a major throughway for Mexican drug cartels.
Awareness is NOT paranoia. It is not only survival but you also can see and learn so many more things about people and life in general when you look it in the eye. AND you just might find that once in a lifetime car find !!!
