Where did you go? Single track trails at Coal Creek (riding area near Oak Ridge, TN) are not marked or difficulty rated. If you went there without a local guide you missed some of the best trails I've ever ridden anywhere. Just abut all the marked trails are crap for dirt bikes.Wish I had gotten the memo about UTV's and rock crawlers before we went, trail difficulty rating must have been based on how big and how many rocks there were!
Some were still fun
