I should also clarify - while I don't go out in the rain, I don't let the threat or possibility of rain stop me from riding. If I get wet, I get wet. Buttttt, I'd prefer to stay dry, and not have to clean the bike, if I don't have to.
Same thing for snow and ice - I don't do either since my crash, because I'd rather not get more stitches.... LOL - but still do occasionally ride during winter, if pavement is dry.
