I ride 11 miles over hill and dell - its a working mans ride. No 3 mile, urban bike path commuting for me.
AND, Im in South Carolina - summers here are brutally hot and steamy. Morning, noon or night, its hot, hot, hot. SO I ride 5-6 months in shorts and sleeves.

Im fortunate that I have a locker room and shower at my job. Without it, I'd have to rely on a butt load of deodorant and just live with being funky.
