If I could choose, I would pick dry weather over rain. But precipitation certainly doesn't keep me from riding. The fact is, I enjoy doing something the majority of other people have difficultly comprehending as viable. That whole don't-want-to-go-with-the-flow thing. Some here have expressed the same thing in why-do-you-commute threads, so I'm pretty confident it is a common feeling a lot of those who frequent this forum have. I have spent an immense amount of time and effort getting my physical self, my gear, and my cycling knowledge to a level where I am comfortable riding in the conditions I ride in. I take advantage of the tools I have to ride just about always.

Oh, and my household is car-light. Driving to work can be a pain for me to coordinate. Nothing better to motivate riding that getting rid of your car.
