Convenient location very near the Beltway (though still a hike from Northern Virginia). I've only been there for martial arts tournaments, so I don't know how it's set up for other activities. But, for large martial arts tournaments, there's plenty of room for 10 or so separate mats. There are also plenty of spectator seats on one side, providing unobstructed views of the activity. And, outside, there appears to be plenty of parking.
