Ive been riding that area for years. If you search you will find some of my threads. Its extremely easy to get lost and most of the trails are on or cross private land so its highly recommended you ride with someone who knows the area. For those reasons you will not find many people willing to just tell you the info. Flask flooding has done a number to the trails over the years. Our club does 2 recruitment rides there every year that used to be called "stocker no locker" but due to conditions 33's are now a requirement. MOst guys who run those trails run big rigs or bouncers.
I believe the only "public" trail is the Daniel Boone Backwoods By-Way through the park. I ride there often, feel free to PM me and join sometime. Might be down next weekend.
