I tend to ride with a saddlebag loaded to the gills, so if I see a broken down cyclist I stop and offer assistance.. as my home is directly on a major cycling route here I often ride upon broken down cyclists, and since my workshop is within hundreds of yards usually I always offer assistance to them.. I have considered rethinking this kindness though, I've had a couple of flats in the last few weeks nearish to home and I've seen riders I've stopped to help and friends of theirs (Yes I recognized the individuals in question) just blow right on by me without even asking if everything was alright.. bike flipped upside down on the side of the road, fumbling through a tool kit etc.. I know I don't help others for karmas sake, but it still royally ticks me off that people who except help don't offer to give it in return.. sorry about the threadjack rant.
