I think the biggest challenge is we have too many events and tracks luring entrants, which is a good problem to have. If someone doesn't like one track, why go there just for a "championship" when they have another more attractive option to them on the same weekend? I think a series works much better in geographic areas where there is one primary track, then they dabble in a couple others such as done in the WDCR.

Maybe there's a way to make it more attractive to people; just not sure how.
