My dad told me that he worked with a man back in the 70's that had a very nice 1957 chevy 2-door car. Stopped at a gas station, went inside. Truck and trailer with a winch pulled up, hooked up, and was gone with his car in about a minute. Someone had been watching and following. I guess the lesson is to keep your eyes peeled and try not to be predictable by driving/parking in the same locations daily. Also, whenever I park my truck somewhere, I try my best to park where it would be a huge inconvenience to try and steal my truck; I avoid the large open area in the back of parking lots.
