New Jersey Drones?

     Here's the SF writer explanation: they're time-traveling camera vehicles, here to record momentous events.

     Momentous events are rarely fun while they're happening.  If I lived in the areas with the most reports, I'd go elsewhere.

     Of course, it could just be the result of population density and a recent change in FAA rules that allows drones to operate after dark -- but there's no fun or profit in that, is there?
