Just found out last friday; there's a meet every other friday in Federal Plaza on Rockville pike in front of silver diner/gamestop/t.j. maxx. So there wont be one this week, but next friday night. People usually show around 10:30-11.
I believe I was the only Mazda there, besides some guy with the loudest speed3 I've ever witnessed. Dunno if he's on here or not. As far as I know, the more the merrier, just don't be obnoxious (I.e. revving/2-stepping/burnouts etc) as per request of rockville city pd.
Help us rep!
