76-year-old rider prepares for 20th MS150

Yesterday's St. Louis Post-Dispatch has an article about Bob Deufel, who is preparing for his 20th MS150 after having two surgeries for aneurisms.
When Deufel got his first job after college, he decided to commute by bike every day. He'd ride 12 miles each way to his position at the University of Indianapolis. "I had another set of clothes in my office there, so I'd change when I got there."

At that point he realized he needed a better bike, so he got a Raleigh three-speed. He still has that bike hanging in his garage.
