One of my fastest commutes of the year this morning. A mtn biker passed me on a hill about 1 mile into my commute, not saying a word. I rarely ever see any other bike commuters, so I was surprised. I drafted him up the hill and dropped him on the downhill without hardly pedaling. Mtn bikes are so slow with knobby tires. That got my adrenalin pumping, so I picked up the pace for the rest of the ride and got to work about 2 minutes faster than usual.
