About 8 years ago some friends of mine caught a guy in Missouri doing the same thing at the put-in for the St. Francis River. Had a person with a camera in the woods, a person in a car down the road blocking the exit and put some shorts and a wallet on the drivers seat and actually left the door unlocked ... did not want the broken window. Nabbed the Jack A$$ ... like candy to a baby. Ended in a chase that was a pretty funny story to hear over the campfire. He ended up going to jail.
Kent - Sorry to hear about that crap.
