There are others,but not in the DC area.Also,these are League locations.You can call them up to see when they run tournaments.For future reference,you can always go Here to look for leagues and Here to look for tournaments.If you click on the tourney link,you will see when my tournaments are at Comic World.Also,always check in this forum as we usually post an announcement for an upcoming tourney.
