Here's a vote for no. Lots of us cross lines across the DMV daily, whether for work or for school or for other reasons. This isn't such a hugely busy forum that it really necessitates breaking it down into multiple smaller forums. If you live in Bethesda or Arlington, are you saying that you really aren't at all interested in classes or camps in parts of DC or vice versa?
Generally, people can always do a better job with their subject lines, but I don't think that's a reason to really split this up.
