My MTB partner and I drove 5-1/2hrs, down to Dickson, TN and rode Montgomery-Bell MTB trails. There's really nice riding, if you don't mind having to pay upfront for every downhill. It seemed like every downhill required a nearly identical climb, before it. Definitely a different type of terrain from what I'm used to at my favorite local trail, as I'm used to a couple heavy climbs, throughout the local system, with much more gradual downhill. The trails were in great shape and we rode ~20 miles. I'd highly recommend the place.
I'm not sure if this gutsy or stupid.
