On Sunday January 27th, I lead another ride in Fort DuPont in SE Washington DC. Had a total of six people join us, including two that had never been in the park before. Rode for a total of about 9 miles. Was nice and slow and involved a lot of talking. http://app.strava.com/activities/38848338
Based on the amount of tire tracks out there, the few people we ran into, and results shown on Strava, a lot more people ride out there than I think.
