So far I've had success showering at home and riding to work and changing there. Seattle weather means it's still below 50 in the morning so far and unless I push hard, I'm not really sweaty when I get to work other than my head. I guess the real test will be in the summer when the morning averages are closer to 60 than 40. I may end up starting my commutes earlier just to get cooler weather in them morning.
