Lets see, I pushed really hard, saw another bike commuter all decked out and thought I would pass him easily, iImagine my surprise when he sped up! Well, I was determined to stay at the same speed, I may not catch him but I wouldn't let him get further ahead! I matched speed with him at around 28 mph. We held that for a mile and he made a right turn (which I was glad he did as 28 was a tad for me but made for a good interval). So I rested, but then came across a police closure of the street I normally use as there was a dead person lying on the side of the road (glad I didn't get up an hour earlier! That would stink to be first person on the scene). So I backtracked and rode an extra mile. All in all it was a pretty wierd commute, I never see commuters, and thankfully never see the other oddity either.
