Commute is 18+ miles each way. Mostly flat MUP, but the last few miles before home require climbing 350' on moderate to steep hills, so a shower is only needed at home. (Wet Ones wipes work great for the morning arrival.) I hadn't bike-commuted in years, but the desire to get back in "century shape" gives me reason to get up an hour early, and my wife usually rides down in the afternoon, so we have a great ride home together, even if it often features a headwind.
My nice day commuter bike is this Marinoni SLX Sports Tourer. I really need to take an up-to-date photo against a better background with the current wheels and Gilles Berthoud saddle.
I'm not so obsessed that I ride when its raining or likely to do so, but sometimes the roads/trails are wet from the previous night, so here's my wet road commuter bike, now with fenders. (No, Mt. Rainier is not on my commuting route):
