I’m certainly not a track manager or race promoter…….. and maybe I’m way off base here…….. but it seems like it could be one of those, “if you open they will come” scenarios.

Maybe start out with a Street car night every other week.
Test n tune and a gamblers race type of thing.
Put it on the schedule so people know you’re open for business.

In any case……. Hopefully they figure out a way to keep the business alive.
