Ballston - Arlington Cemetery, Hwy 66 - GeorgeTown - Key Bridge - Ballston
A trail that looks like a hammer. I went down Willson Blvd. to Arlington Cemetery, joined the Mt. Vernon trail south and hopped on to the trail on 66 in to DC. Then I walked along the Rockcreek park trail north to M St. in Georgetown until Key bridge, back to Arlington VA and then to Wilson Blvd. and back home.
