18 cars, with 3-4 people per car in pits and 300 people in stands to watch sprints specifically is what it takes to break even on a very modest $800 to win sprint purse...thst is if u can get a total of about another 80 cars in other 4 classes and hope like no other another 350 people show up in grandstands. I'm not against sprint cars. I love them and a lot of my friends run them...Cottle, Stockon, Maddox, Short, Cockrum..etc but if, as promoters ,we don't watch our financial facts closely, we will be just another closed race track.
