I went to 20 Knoxville Nationals without wings, 1961-1981, for some reason they ran wings in 1973. Knoxville was just too big and fast to continue without wings at that time. A lot of bad stuff happened during this time. After the Gary Scott fatality in 1982 wings have been the norm at Knoxville. I know people that stopped going because they didn't like wings. Now most people there wouldn't go if they didn't run wings. Crowds were never very good the few times they ran wingless since.
