Awesome singletrack that has it all. Starts with a fun decent off an old bunker into paved road. Dumps you into tight singletrack with a bunch of tricky rock and roots as you weave around. Have option to bail out twice - one going out to paved road, second towards the last quarter of the trail on the left. Go right up the hill and hit that chunky tech with sweet rock climbs then descend down to the street.
