My commute is a measly 3.5 miles each way but it starts right off with a big-arse hill that gets me all sweaty. In this cold weather, I can take the hill slow and be okay but when it warms up I'll be a stinky mess by the time I get to work so I've decided to do the ultimate Fred move and WALK the dang hill.
When spring and summer get here, I'll still have to do the paper towel bath when I get to work; ain't no deodorant powerful enough to overcome Alabama heat and humidity.
I have the under-saddle bag that holds tools, tube, patch kit; a rack and some plastic fenders that I usually have off. Blinkies on the front bars and a Planet Bike blinkie for the rear.
I find that yelling at the crackheads usually gets them out of the way in the mornings. In the afternoon I brandish the frame pump. They show respect.
