I remember I helped a guy a couple years ago, two other fellows were stopped too, but when they had the tire fixed the chain had looped around itself and I was able to help unsure it. Also, one of the Ride the River ride on the Mississippi River, my dad got a flat and a cyclist in a car stopped and asked if we needed help and was quite insistent on helping us, though he had everything taken care of. I like the previous comment about belonging to a community, that's what I think most of us try to be part of.
