The ride starts at the Flatwoods Station on the east side of the park. You have to pay the ranger 5 dollars, because it is after hours.
The ride rolls out at 6:30 and the typical route is down the 1800 trail until the Eubanks Pwy and then back up to the "Y". Through the center of Flatwoods. Cross the pavement and then up to the levy. Take the trails up to the south end of the levy turn around at the bridge over the river and return the same way. If you do that route in both directions it will come in at around 17.5 to 18 miles. Some of the folks will ride Panther and Squiggy as well. BRIGHT light is needed. There is little to no ambient light.
