The route starts off South St., just past Davidson Elementary. From there you will go behind The Pines, then up Avinger Ln., then right onto Pine Rd. Turn left onto Patrick Johnston, down the hill, and back on the greenway. At the Robert Walker Ext. you can either continue straight and stop at the terminus, or you can go left toward Concord Rd.
