I got a new set of tires for my commuter bike today, and guess what happened on my way home? Flat. Gol-dang kids and their soda-pop bottles. Fortunately, I had a spare tube, so after a gigazillion strokes of my mini/micro/nano-pump, I was back in action. I even deposited the vitrious instrument of mass deflation in a nearby recycling facility, cuz that’s the kind of responsible earth citizen I am.
