For weeks now, I have been trying to solve a mystery. This morning, I did so with the aid of my drone. With Swiss clock precision, at 6:55 AM, a half dozen or so cars will pull into the parking lot across from our house and line up in a row. At 7 AM, a large van pulls up and some kind of exchange occurs after which the cars drive away one at a time and then the van pulls away. For weeks I have assigned nefarious explanations to this carefully synchronized exchange only able to observe it from the ground level and at quite a distance. It appeared that the driver of the van was distributing something to the drivers of the cars and then they immediately drove off. For a while this seemed to be happening every day and then it stopped. With the benefit of an aerial view, the mystery has been solved. The cars are dropping kids off for some private school to which they are shuttled. It is a shame the explanation is so mundane. I had developed a number of mystery show worth explanations that were far more exciting. The break in routine was due to holiday vacations. What I thought was the driver returning from the cars were the kids sequentially leaving their cars for the shuttle.
