Today was a 22 mile RT commute, a pleasant 15 miles in the am and 7 miles on the way home in the pm. It started raining pretty good an hour before I left for home, so I unrolled the rain jacket and took the shorter 7 mile route home instead of my usual 10 mile route. Here in southern cal, rain is pretty rare and the problem is when it finally does rain hard enough, there is so much accumulated crud on the streets that is lays down a pretty thick layer of goop onto the rims. Of course, I ride with full fenders and flaps so it doesn't splash onto me or most of the bike, but it takes a while to clean the rims off when I get home.
