Long story short, our apartment building has a fire safety guard 24/7/365. I get along particularly well with one of them. When he's on days, he sees me go out for rides and was inspired to get on his old Peugeot and do the bike commute from Crown Heights all the way up here to Washington Heights (something between 12-15 miles I estimate). I even rode part of his commute home with him one day by sheer coicidence as I was on my way to a bike safety rally at City Hall. Problem is, he's been getting lots of flats. The wife and I come home late tonight from a small show downtown to see this guy starting his night shift with a tube and some of the nastiest, old patches I've ever seen in his hands, shaking his head in frustration. The tube is covered in these patches and he's having trouble finding the latest leak on the tube. Five minutes later I am down there with a fresh tube so he could make it home and a real patch so he could see what to buy next time (fortunately we had some Schraeder valve tubes around for the wife's hybrid). He was relieved and thankful; I feel warm and fuzzy all over.
