I am looking for a place to watch the games this season. Is the club active?

How far are you from Jimmy's Tavern in Herndon VA? If it's a short drive, I'd recommend it. The owner is a Bills and Sabres fanatic and they serve good wings (use Anchor Bar sauce) and a fantastic beef on a weck.

There is a DC club linked to Buffalo Bills Backers of NYC at McFaddens and it appears active.

Personally even though it is closer I prefer to gp to Jimmy's even passing Greevey's to get there.
But I am the co-founder / vp of the Bills Backers of Northern Virginia so you would expect me to say that.

I do agree with Rich about Beef on Wech there.
Jimmy found a local bakery to make them just for him.

After the Bills-Skins game last year, I hitched a ride back to DC with the McFaddens crew, only to get back to McFaddens and find it CLOSED...Six o'clock on a Sunday night, the place is sealed tighter than a drum! I was looking forward to getting a plate of wings and a pop before going home and McFaddens was shut down...
