9:00 Arrive at Mark's house, trade my car for his bike
10:20 Arrive at work
Final score: 120 miles, two and a half hours, three bridges, two major traffic jams. On the flip side, it's a fun bike to ride-- surprisingly so, given that it's 20 years old.
The biggest downside? The riding position is just a hair too aggressive for me. I'm getting old, and my knees don't bend that way anymore.
