Today was the first hard rain I have bicycle commuted in, and it felt good, both during the ride and after I got to work and felt some victory over the elements for today.
I actually saw one other bicyclist out in the downpour. It was a guy on a bicycle that looked like an imitation motorcycle chopper (don't know how else to describe it). I did a double-take, wondering if I was imagining it, and if it was to be followed by purple unicorns or something. Just some guy biking in the rain on a chopper-looking bike. On the sidewalk. Weird....
Changing out of wet clothes in the bathroom stall was less pleasant than usual, but can be done. Overall, a great commute.
