I neglected to post this photo when I took it . . . uh . . . August 9. On my first off-read bike excursion after buying my Schwinn Mesa mountain bike, I took the Cross County Trail north from Georgetown Pike into Great Falls National Park. The trail terminates at the Potomac River where the Difficult Run creek meets the Potomac.
Needless to say, it is pretty incredible how much beatiful stuff there is within a short distance of Washington, DC. Even in urban Fairfax County, sights such as this can be found—if you know where to look.
