One thing about the nascar trucks is they cannot have a tacky dirt track to run on. They can't do it. Bristol showed that. They ran one lap and no one could see out the windshield.
Red flag.
Wait for later.
The trucks still have their glass or whatever windshields in so a dirt track basically has to be like asphalt for them. If knoxville has a lot of rain and still can run the sprints, I think they will, if nothing else, as a way to dry out the track.
