Fun single track with some very technical hills and cutbacks. Those are still unridable but not to many to make it not fun. The kids can't go or it's total hike a bike. Some fun straight aways
Leave going North of Manhattan Kansas on tuttle creek blvd. Turn north to go over the resevoirs Damn. Watch for the turn on the left after about 10 miles. The sign for the area will be at that left turn. take it. follow the road another 8 miles or so until you so the entrance to Carnahan on the left side of the road. Enjoy.
