I've never had any camera gear stolen but someone lifted a nice suede jacket from my car once.

My father's car was stolen from a gas station once, literally inches from him, this guy just jumped in the car, cranked it up and drove off... besides his leather jacket and the car stereo, there were about 40 gallons of microfiche chemistry in the trunk that were not in the car when it was recovered.. we always wondered what the thief did with that stuff, it's not like it had any resale value, or anybody who wasn't already one of Dad's accounts would have bought it...
