Well, it took me over a year and a half, but I finally managed to break two rear spokes last night on the commute home. I definitely need to lose a few more. I can't complain, though - my bike is a POS BD dawes Lightning "sport." About 1000 miles before they broke.
I did learn that I need to carry a couple of hex keys with me. I rode it home the 3.5 miles to go, but had I a hex key, i wouldn't have had to fight the rear brakes the whole way back.
