I see inline skaters the most on the mount vernon trail but that is because of where i live. https://www.nps.gov/gwmp/planyourvisit/mtvernontrail.htm

There are probably other popular places right in dc.

The number of theaters and theater companies, the number of music venues, the museums, the monuments, the trees, the book stores, and the roller rinks. We've got SIX rollerrinks nearby including the only roller rink that is part of a national park.

I dont want to see that play. Really, well there are several others playing the same night. It is an embarrassment of cultural riches.

Plus you are in driving range of beaches and mountains.

And three airports.

And it is still CC.
