Here I am standing almost at the top of the railroad bridge that crosses the Cape Cod canal. I was invited to come for a visit and watch the bridge go up and down for the Cape Cod trash train.
As the train was approaching the attendant asked if I'd like to lower the bridge. "You bet!" I said and was shown how to do it - there's a whole protocol and you have to watch the lights on the operator's board to make sure everything is going properly. The train crossed the bridge without a mishap thanks to my flawless operation.
My friend Bob who was visiting with me got to raise the bridge. It was fun all around.
