yeah, what crays said. There is established precedence that the airspace, at least to some degree, is that of the property owner. Otherwise, I could extend a 2nd floor balcony over the back yard of my next door neighbor. I won’t water the street to keep folks off public property, but I will water my own lawn when I want (there was a funny video posted on this site of someone doing just that, using a motion-activated sprayer, to keep trespassing pissers at bay).
