As I was finishing up fixing my flat today, a rider came by and stopped and asked me how far I was from my car (actually, my car was at home, which was about 13 miles away) as if that was the solution to my problem. I told him everything was under control as I carried two tubes, a patch kit and a great Topeak pump (Road Morph). He seemed surprised and mentioned to me that perhaps he ought to carry something - he had absolutely nothing with him. I agreed whole heartedly with him!! BTW, I had several other riders ask if I was OK, which is sort of nice - I do the same thing.
In fact, I stopped on the Waterton Canyon trail for a damsel in distress - riding a department store Magma. The pedal had come off. Sadly, the threads were stripped so bad there was nothing I could do to help, except to advise her that it was possible to ride back using one pedal and coasting (the trip back was mostly downhill).
