It's not 90 acres, but it's a good chunk. We have been riding the track for about 2-3 years now. It is NOT, repeat -NOT- currently public. It's basically an invite only situation right now.
Come spring this may have changed but the folks who own the land and are actuallypushing everything through vow it will go through.
Last I knew I believe they were awarded the permits to allow it to become a legit pay-to-practice track. But I haven't spoken with the owners in about 2 months so I am not sure the exact current status.
As for the actual track, we still have a -lot- of work to do but it's getting there. A looooong way from race quality, but it's a nice practice track at this point.
