Seemed like a normal early evening outside the Clarendon Metro station Friday, according to this very fun video. Some firetrucks screaming past. And then, some belly dancing erupted. And soon, a lot of people were shimmying. And then, they were gone.
Arlnow.com alerted us to this, and notes that it was organized by the Saffron Dance school, also in Clarendon. Either they have a lot of students who were in on this, or belly dancing can turn an innocent bystander into a sultry sorceress.
