While road bike style tires create less friction as they move across the pavement, it is worth remembering that they perform poorly in some situations. For instance, when a crowd has gathered atop a bike path in order to watch a Blues Festival show for free, prompting you to try riding beside the path instead. It is then that you might get a rude reminder that 110 psi + slick tires + any surface that is loose or slippery + tires not perpendicular to the ground = spectacular deviations from the normal arrangement of bike, rider, and pavement.
Miraculously, while my digicam managed to tear through my pocket as it abraded across the pavement, it seems to be only cosmetically damaged. The flow of daily photos should continue.
P.S. Incidentally, it seems my front wheel and/or front v-brake is bolloxed. As such, cycling shall be discontinued until repairs are complete.
[Update: 7 July 2008] The good people at G.M. Bertrand repaired my brake and tire for free, further deepening my conviction that they are the best bike shop in town. They also adjusted my shifters, gratis.
