This event ran as many as 21 heat races a night, plus A features, B features and races of champions. They start racing at 3 p.m., and ran as late as 2 a.m., with only breaks for track prep.

I have been to a lot of races over 35 years, but I've never seen anything else ran with the precision of the Boone Super Nationals.
