Suppose it's a rule where a USAC points driver can only race a sprint car at a non-USAC event at a track that is has a USAC sprint car date. Would that perhaps be a small reason why Granite City suddenly has a USAC sprint show? Seeing as they run 3 nights of unsanctioned sprints with the Gold Crown? Whatever the rule is, I can assure you that the USAC midget drivers will be able to jump in sprint car at the Gold Crown without hurting their standing with the USAC sprint division.
