I was looking at some camping reservations and noticed these banners on the side of the US Forest Service page. Do you think it only applies to multi-rotors? what do they consider a drone? My airplanes are not drones? I may have inadvertently broken this unknown rule a few times. Is this an FAA rule? I know FROM FLYING GA, that in some National park areas you need to maintain 2,000 AGL. Jeeez, you need a degree to know all the rules!
