7 miles @ ~12 min/mi

Daughter has Saturday morning orchestra rehearsal in Falls Church VA, so GPS-equipped I head south from Route 7 in search of the W&OD Trail ... foolishly venture through some woods near the Beltway (lots of poison ivy — ugh!), emerge in sombody's back yard, and eventually find the trail near milepost 8.5 ... three measured miles along it and then back to the orchestra site ... I acquire latitudes and longitudes of four W&OD markers to add to my GPS coordinate collection ...
