Hi!! New to group!

A group of us are going to Fall Branch (near tri-cities) to a friends farm in a couple weeks, and was wondering if you knew of any great trails up in that area. We have done most of the trails here in our area (BSF, Smokies, Bakers Creek, Norris, Citico, Farrs Gap, Coker Creek, Panther Creek, Rarity Bay, etc.) Looking to see if there are any good ones up near tri-cities? I have 2 horses (TN Walking horses - Midnight and Renegade), but will most likely take Midnight. Reni is still in training but is doing beautifully. I want to do Lone Mountain sometime in the near future, too. Anyone heard of the Lovingood trail challenge in Oct? I would love to do that.
