Unfortunately, I'm not in Fairfax at all -- I work from home in Ellicott City, just south of Baltimore. If you had to wait for me to get to Fairfax after work, it would probably make us really late to the sing. Rockville might be about halfway between Fairfax and Ellicott City, though, and is on the way to Frederick. Or we could just try to meet in Frederick at 7 or so and eat there.
