Sunday I rode the North Branch trail starting on the north side of Chicago and flatted. I think it's interesting who asked if I was ok. Approximately 25 people rode by while I was on the side of the path, and the the only two who asked if I needed help were road bike riders, and they were the only road bike riders I saw. Everyone else was riding comfort or mountain bikes. So was it a matter of roadies helping out another roadie, or the others thinking that they wouldn't be able to help as I may have looked to them like I knew what I was doing? Or were people just not willing to bother?
BTW - that trail is not a great place to ride a road bike on a Sunday afternoon. I felt much safer on the streets before and after than on that busy trail with cyclists that didn't seem to have the very good bike handling skills, and with peds meandering all over the path.
