THIS is the gym you are talking about:
I trained there for a week when I had work im Potomac, MD (15 mins drive). The place is awesome, have 3 racks, deadlift platform, forza bench, olympic bars, chains, boards, bands, GhR, tire, farmer walks, prowler... it is in a small warehouse district so there are no college dbags around. I can't recommend it enough - great place - Matt Gary and his wife, Sioux-Z are great folks and willing to help. They are not expensive either.
If you can't make that place (although I seriously advice you to try it) see this:
