Trail along the water from the boat ramp is ueber technical but gets worse once past the "Kissing Oaks" (two oak trees that have grown into one another). From there, you can follow the trail back down to the water's edge and ride to the end, looping back on the forest road. Many unmarked trails throughout the forest.
Review: I rode the Upper Gussy Trail to the intersection with Brody Road, then rode a few side trails near Hanover road. Some pretty rough terrain for the most part but I am pretty new at this. Some of the hills are too steep for me to climb and parts of the trail are too rocky. Overall though it was a good ride, just required technical skills that I currently lack.
