Drag track combined with speedway

Lebanon Valley Raceway (I think that's the name), in New York, has a dirt oval w/ their drag strip. We went to a NHRA points race there one weekend. After we left the track on Saturday for the motel, they had a race on the dirt. EVERY car in the drag pits was covered w/ a 1/4" of dirt the next morning! So, in addition to the usual nervousness of getting ready for the first round of the day, we all had to clean up first!
Our neighbor was under his car, when the stream of muddy water ran right where he was working... Uh oh. My partner and he seemed to have different opinions of what happened, considering the tension in the air about first round. We survived, went 2 or 3 rounds, as I remember.
