My bonehead stunt of the week was, fortunately, a near-miss. I rode up to a stop sign at a t-intersection, did a mini track stand, looked both ways, all clear, and started to go. Then I heard a familiar sound of fast-moving carbon fiber, so I stopped. Almost got t-boned by a ninja rider in all-black kit on an all-black bike coming fast in the shade under the big trees. It would have been my fault. Glad it ended ok.
