Honestly, I think the Fremont/Attica comparison is much better than the Knoxville one. Fremont and Attica seem to have more in common with the Indiana tracks. In my opinion they seem to have around the same size of fan base and bleachers. Knoxville is huge and holds the biggest sprint race on the planet, nothing in Indiana compares.

So I think it's a fair question why 2 tracks in small town Ohio can pay double what any Indiana track pays weekly. With the die hard fan base in Indiana I seems like a valid question.
