I was driving down the highway a couple of years ago, going around 120 or something, and I passed a dude with a dog in the bed of his pick up truck!
I slowed down and fumbled to take my digital camera out of my purse to take a pic of the poor dog, and his license plate to give it to the cops. My picture came out fuzzy (I know I shouldn't have been driving and trying to mess with a camera) and the guy got off the highway a couple of exits later, so I really didn't have anything to bring the cops. Unfortunately. I really was going to report him, but I couldn't get a clear pic of his license plate.
