Nobody who looks like a commuter-by-choice, anywhere. Maybe 2 sometime-commuters that I have seen on the roads.
In 2+ years of riding, I saw a kid who looked like he was going to school (and riding on the wrong side of the road and weaving all over), one time. I saw a no-helmet slow guy who looked like a DUI refugee, one time. I saw a young man whose car broke down riding to work in the middle of the night in the winter with no lights; I stopped to chat, he asked to follow me to take advantage of my lights, but I couldn't ride slow enough to hang on to him despide riding about 10 MPH and circling back to pick him up 3 times, he eventually just stopped.
There's a 50-something asian guy who I've seen on my route about a half dozen times, riding pretty slow. There is a guy who looks homeless or at least poor, riding a walmart beater and always has a big plastic bag full of returnable bottles and often stops to pick some up; I see him about 3x a year.
There's a woman at work who I talk to occasionally, and she rode to work... one time. There is a beat-up 10 speed that shows up at one of the entrances about 3 times a year, I don't know the owner.
