One of my neighbors is into drones and he was down at our local baseball field, nobody else around, test flying a drone that he had just did some work to. A deputy came driving in and got right nasty with him about it. People fly kites there, throw frisbees, run RC cars and all kinds of stuff, so I don't get why drones are causing such a freak-out.
What's the (real/actual/potential) problem?
