The key was mentioned a few threads up. Promotion. Its all about promotion, advertisement and sponsorship. The last one man promotor and bank roll was Earl. He never took corporate money until the Mopar Million. In today's world this business model doesn't work. You must seek external funds beyond the front and back gate. If you can find local businesses to support some special race nights or add to the purse then the burden isn't on the admission and promotor.

Look at how Knoxville does its weekly shows. Its typically some sort of "night"..... Vermeer Night, 3M Night, Pella Motors Night, Casey's General Stores Night....... See where I"m going here?? The additional funds for those purses are coming from external sources that don't impact the gate. Those sponsors get their money back in return by the fans being consumers 10x. Race fans support what supports them....this where I don't see local tracks do enough to pull in the extra funds for larger purses.
