I was in Ft. Wayne IN for two months. You always ran into the same people on the trails there. There was this guy, John, who had to have been about 75. He'd smoke his pipe while riding his bike! Very cool, very slow.

Then there's this fat-ish guy who hauls a big cooler with his MTB on a modified Bob Yak. He zooms around at around 18mph. Never stopped him to ask what was in the cooler. One can only imagine.
