i assume that you have the old course maps and the flatrock trail maps. after the downhill that comes after crossing the powerline, the first left of significance should be after a steep, double track to single track uphill climb after the initial downhill. it should be pretty apparent where the left is b/c there usually is a stick delineating the left hand turn to funnel you to the ridgeline and keep you from doing a short downhill back to the road. if you have any questions, hit up the mountain bikers of michaux website. they usually do a preride of all the race courses a week or 2 b4 the races.
