After reading the information and their comments on their web site I've come to the conclusion they don't have a clue to the magnatude or funding requirements necessary. If it happens in 10 years I'll be surprised.
just read through their website.
not surprisingly they're still (as of November-January) scouting locations and trying to make inroads with different county officials. 4, maybe 5 counties are up for consideration. Everything is conceptual at this point. The scale of what they have in mind is mindboggling and very, very, very expensive. Wish them the best of luck and I'm certainly motivated to help a racetrack get started but realistically the chances of seeing it fruition are questionable.
