Ginsberg and I were at the Richmond go-kart track. He was on my bumper for10-12 laps. We were having a good race. They continued to give me the blue flag. Then they gave us BOTH black flags. When I stopped they said "We kept giving you the blue flag, you HAVE to move out of the way when we give you the blue flag". I then began to give them a few choice words and haven't been back since.
