If you are in NoVA you are "in market" for the caps and so 100% of the caps game should be blacked out. It sucks if you don't want to have cable and still watch the caps.
I'm in San Francisco and I get all of the caps games except for most of the nationally televised games and it's great. But in market...you have to get cable or find illegal streams. Sucks for those of us trying to cut the cord.
