I am a lawyer in Chicago, and a fair weather cylcing commuter, which accounts for most of my 2,000 - 3,000 miles a year. I learned that not having a monthly rail pass is an incentive to get on the bike in the morning. I am extemely frugal. I have a 1983 Trek touring bike, which I bought used from a friend in 1986 or so. It has worked very well for me.
I was looking for advice on various bike questions, and found this forum.
