My 13 year old son and I went to ride the Devil's Den trails today in NW Arkansas. I rode a race there about 4 years ago, but today was my first time since then. It was excellent. Those ozarkoffroaders have done some great work there. We would have spent the day there except for a mechanical on my son's bike, but we still got in several miles anyway. Cool spot to ride if anyone is looking in that area...
