I ran into some trouble on my ride today. A piece of copper wire punctured my tire and I had abandoned ship on the side of the road. I stood on the side of the road awaiting help to arrive. During that time, about 15 cyclist rode by... One of them stopped to offer help.
Funny enough, I came home to patch up my tube, and I went out again. During my ride, I came across someone with a broken chain... You bet I made sure I stopped to offer any assistance I could.
I wasn't expecting anyone else to donate their own tube for my benefit... It was just a neat 'accidental' experiment to see how many would offer their help.
What about you guys? What's your ratio of "stop and help" vs. "ride-on"?
