There's something about a good aggressive ride that makes one... well, you know: aggressive. It goes with the territory. I've been trying, lately, to ride slowly enough to not break a sweat; I'd like to wear more 'adult' clothes to work, and maintain an appearance that conveys a little bit of my phd-level respectability. But I just can't handle it when another bicyclist passes me. Without any conscious effort on my part, my speed goes from 14 mph to 18 mph and.... dang, where's the smiley for "hot and sweaty"?
