I answered this question in another forum some time ago. It's only a few to a handful of states that prohibit both hunting and fishing with a drone.We've used kites for many many years in both state & federal waters to carry bait/lures in positions & distances from the boat. No regs against it. Cant see a UAV any difference in using kites.
Hunting is a different critter. Many states dont allow baiting/feeders, etc. I can see how UAV would prohibited.
