Another issue would be criminal liability. The border of you property theoretically goes up to infinity, so if a drone is "on your property," it is trespassing, and the pilot could be arrested, depending on local laws and evidence.
Being from Texas, I'd say that drones would be much cheaper than skeet, at least for me, since I won't pay for the (ex)drone, and I have to pay for the clay pigeons. Too bad, I'm inside city limits again. In the counties, you can pretty much shoot anywhere, anytime, as long as you have permission to be there, aren't breaking game laws, and aren't threatening anyone or their property. Trespassers are like coyotes; always in season.
