Noob,
Iv'e heard from friends that it is officially off limits, but since then they have riden there. I get the impression that if you go, you take your chances on being thrown out. That's all just hearsay, but since there were no other replies, I figured I'd offer it.
We live in Medina Co. so were pretty close to you, where else do you ride? Ever been to Crow Canyon? Lightning? Elson St.? Bear Creek? Apple Cabin? Battlesburg? What kind of riding do you like? I prefer trails but my son and his crew all race MX so we usually try to find both if we all go together.
