Most of my riding now is for exercise. When I was younger (as in back in the 70s younger) I rode my bike back and forth to work - as an auto technician - during the days of the gas crisis. 8 miles each way, and my boss made sure I had a secure place to store my bike during the day. I ended up fixing up some old bikes for some of the other techs who lived less that 2 miles away, and soon half the shop was commuting by bicycle to work on people's cars. The owner took a picture of the shop crew and our bicycles, and ran an ad in the newspaper that read something like "Our technicians know there's only one way to get better mileage than a tune up at XYZ"
