I had taken this approximate route as far as Peirce Mill in Rock Creek Park before. This time, I decided to keep going and hop on the Metro when I was done. I took the path as far as the Potomac, and I was prepared to finish at the Foggy Bottom Metro. But, hey, I was in DC by the monuments, why not ride around? So I headed up Constitution, past everybody who had gotten into town early for Rolling Thunder, and then to the Archives/Navy Memorial Station. That allowed more sight-seeing, a delicious frozen mango treat, and a straight shot home on the Green Line. A version of this trip is also available at Everytrail.
