I do go to drives with M Club of DC (Skyline Dr, Sugarloaf Mountain, etc.), that's fun with 10-20 M cars and every now and then to Katie's Cars & Coffee in Great Falls or Dulles Cars & Coffee near Aldie off of route 50.
Yeah, come by to Dulles Cars & Coffee this Sunday I'd probably go there this weekend (6:30-9:00am) - 24560 Dulles Landing Dr Unit 110, Dulles, VA 20166.
