Fairfax, Virginia. I have 10-11 in a 20 mile radius however I can't remember the last one that was built. I do, however, know the last one to be renovated if that counts. AMF in Centreville semi renovated when they wanted to turn the place into a gay bar back in 2007 but plans fell under, so now they're just open play with one 10 team sanctioned and a small handfull of fun leagues. Next would be either Bowl America Falls Church which used to be a locally owned business (they had duckpins!) and probably US Bowling out in Alexandria, heard it looks a lot nicer now than before. Did a youth tournament there back in the 90's wasn't too impressed but then again I was only 15. I'm giving it time before the lease runs out on some of the BA's around the area and Brunsiwck comes in and makes them Zones.
