Chain Bridge to the Beltway along the CNO canal; Nov 4, 2012 (11 miles): 20 Oct, 2012 (11 miles)

I drove to Chain Bridge, parked there, crossed the bridge to Maryland, got on to the CNO canal and headed North until the beltway. Turned around at the beltway and got home. It was very foggy in the morning and I enjoyed the eerie ambiance.
