We had a little friendly competition from a guy on a fixed gear this morning. He turned onto the road ahead of us, but wasn't carrying much speed, so we caught and passed him almost immediately. Next, he rolled through two stop signs we stopped at, but wasn't able to keep up on the DH. We saw him a couple more times heading into downtown, where he tended to filter and jump lights, but not flagrantly. I had fun chasing/leading him, but I think I had the advantage with a higher gear.
