The local strip here is just for drag racing but to help pay the cost,he also does outdoor concerts,bike rallies,Harley drags,.Just about anything you can think of for outdoors.
People come from out of state for the Harley drags,only draw back is the Banditos Bike club run the event...Support your local Bandito..woot woot.
Anyway my point is.
If you could get enough people interested and willing to donate,you could have a track built and offset costs using it for other events besides racing.
The track itself doesn't need to be anything impressive...concrete launch pad with concrete retainers ,asphalt racing and shutdown area and safety barrier.Thats where all the money is.Outside of that the place can grow as the profits grow.
If there are so many people interested,then all it needs is someone to organize the effort.
Just a thought.....
