...I didn't think I was that heavy. I figured this was the sort of thing that happens to other people. Apparently I'm not immune.
While trying to outrun a storm on the way home this evening I decided to take the most direct route, which takes me up the Oakmonster (a steep hill up Oakmont Boulevard). The storm was behind me, but gaining quickly, and the atmospheric pressure in the storm was low enough that it was sucking all the air from in front of me into into the thunderhead, creating a stiff headwind. Hill + Headwind + Nervous Clyde... I guess it was inevitable.
I broke a spoke!
