Yup - I live in Arlington, work in Tysons. It's a mostly uphill ride to work, but my legs thank me at the end of the day.

Although today's ride was a bit of a disappointment... I wanted to use the air compressor off the W&OD in Falls Church to fill my rear tire (I can't seem to max it out with my pump), but someone must have pulled the valve off the end of the hose... so it's worthless. With the heavier load on the rack, I could really use some extra air in that tire.
