This is on the other side of the road from Rockville park. Did a tour with them about 2 weeks ago (actually the one in the picture). This is a new area that is currently only open for bike/hikes during these events, but should eventually be open to all. Nothing super exciting, but cool landscape, and a lot of potential. They are also looking for people to volunteer, and become docents as well. Pretty good gig, and nice to see something new. I think we did about 10 miles or so and 1300 climb when we did the ride before.
