Sadly this turned out to be a non-ride. I stopped some MRI and CT scans off down in Silver Spring for Rebecca's sister then I headed up through heavy traffic and seemingly endless red lights to Duncan's house. Unfortunately, Duncan noticed a nail in his rear tire so that scrapped our ride plans. I helped him remove the rear wheel. We took it up to Bobs for a quick replacement instead of spending the extra time to do it ourselves.
By the time we got the tools we needed and were back home there was just enough time to mount the wheel and call it a day.
