I did one of these a few years ago, and really enjoyed it. Knowledgeable ride leader, saw new places, etc. I’ve been meaning to do it every year since, but always seem to end up out of town. If you’re around the weekend of May 21st, check ’em out. (All free, too.)
(And I would *love* to see something like these for Arlington.)
Cool link, sir. Looks like it could be fun. I’ve been wanting to put together a “Statue of a Dead Guy on a Horse” tour of DC by bike. It would probably end up being a double century though.
