I commented online about this. I believe its a fabrication. I spent all day Saturday at this junction(fun run checkpoint). Its a flat treed area next the the junction. Maybe a total elevation change of 2 ft on the north side.
The south side has maybe a ten to twelve foot elevation change. But its heavily treed and flat and not really anywhere to ride. I can say there was not a single track off the south side of the road within a 1/4 mile of the junction.
