One of my sons friends gave him a drone the size of a matchbox. He was flying it around the house, drove the dogs nuts!
It's a toy-drone, but so are some video cameras today-the tech for both are here, and cheap.
In between these extremes, there will be a zillion drones available for different prices. There are not enough eyes at the FAA to police this.
I can see some crowded anchorages like Block Island, looking a little futuristic with these things buzzing overhead on July 4th.
Maybe a simple jamming device that sends them into a nose dive, will be available soon, as an app. Then it could be fun for everyone.
