I looked into going there for a Radford game in December. Very little parking. There’s a nearby metro but it doesn’t look like a great area. Anyone been there?
I have not been there, but I understand it's about a five-minute walk from the Congress Heights Metro stop. I doubt I'd worry much if I were going to a game there, as I'd figure the presence of other people going to the same event might help ("safety in numbers" kind of thing), similar to how I never worried much about parking down in Buzzard Point for Nats games in the years before Audi Field construction began.
I'm not sure I'd feel comfortable in that part of town if I were not attending a game, however. I've driven through that area on Martin Luther King Avenue. It's certainly not the roughest part of DC I've ever been to by any means, but I don't feel it's an area where I'd belong.
