I had one incident...
A guy in the parking lot of Ct. Dragway (1971) ran over my foot then laughed. I yelled at him and he gave me the finger. He had to stop about 20 feet away for traffic so my girlfriend ran up to the passenger side of the van (Window open) and punched his girlfriend in the face, knocking her out. The guy got out of the van and chased her... But he got his foot ran over by another car that was leaving.... HAAAAAA!
I've been telling this story for 42 years and still laugh about it!!!!
