Supply and Demand. There is very little demand for an afternoon race. For all of the reasons mentioned above.

I have gone to several Knoxville Nationals that would have 20K fans for the Saturday finale. However, if one of the qualifying races gets rained out and runs on Saturday afternoon, they have closer to 3k to 4k fans for the afternoon race. All of the fans are already in town. All of the fans are already die hard fans to drive to Knoxville, Iowa in August. But 3 out of 4 of these fans would rather do something else than go to an afternoon race.
