I have a six foot high fence on all sides, and my neighborhood is almost deathly quiet.
My wife loves to garden, and the backyard is like the Garden of Eden to me. I have a structure built in one corner of the yard with a large hammock, and a nearly unobstructed view of the Northern sky.
I value it most among any earthly possession, that beautiful back yard. When I get home from work, if the weather is above 60, I grab a beer and my pipe, and go out there and have a smoke, looking at those stars, listening to the wind through the trees.
About two years ago, the old woman behind us who had been renting the house for years passed on, and a group of what looks like three sixty-or-seventry plus year old couples moved in. It is a small ranch, but...I guess it is okay for them. They also leave their lights on in the house all night, which now has light where there never was before, but what would I say? Can't say anything, and...I wouldn't. THAT isn't much of a big deal.
My only exposure to them had been when I was fogging my yard for mosquitoes, and I didn't realize they were having a cookout or something, and the guy stuck his head over the fence and yelled because he thought my yard was on fire. (there is a lot of thick white mist when I fog) I apologized and explained, and said I wouldn't do it again without checking first to see if they were out there, and I offered to fog their yard anytime if they wanted to have a party. But that was my only real encounter with them.
So if they left their interior lights and windows with no drapes on all night, I conceded it was not my business.
They don't make a lot of noise, but early last spring, they put couches in their back yard and put a fire pit in.
I think I would have been fine with that, but...they installed a series of about 10-20 party lights on a wire in a rectangle around their fire pits and couches. And they weren't Japanese lantern or Christmas types of lights...they were those spherical round bulbs that have a great big huge filament in them.
When they turned them on, the entire neighborhood lit up with bright white light for at least six quarter acre lots. And they left them on all the time. It was like having five cars parked facing the back of the house with their headlights on high beam. All the time.
Just 15 yards from my hammock.
It began to make me feel nearly crazy. I would grit my teeth just looking in the backyard, and would mumble and mutter. I began to think about taking out the lights with a BB gun or something, crazy stuff I would never do, but it began to pass my thoughts.
My wife suggested I just go talk to them. After about two months of it, I came to think that perhaps they actually really were oblivious. I couldn't see how that could be the case, but...I didn't have a lot of options.
Well, we have grapes that grow all around my hammock, and we had a bumper crop last year, so I picked out the finest and biggest ones, and went around the block to knock on their front door.
An older woman answered the door (this was the stupid "COVID Spring) and I introduced myself as the guy who lived behind them, and said I wanted to give them some grapes from my yard. And then I said:
"I actually came over for another reason. I saw you guys had put up some party lights in your backyard, and they are really, really bright. One of my joys in life is being able to lay in my hammock and look at the stars, but the lights drown out everything and light up everything, and...I don't think you do it intentionally, but you leave the lights on all the time. Before I continue, let me say: I know this is your yard, and if you want to keep the lights on all the time, there isn't anything I can say, because it is up to you, and I won't bother you with it. It is your choice. But if you could, would it be possible to keep the lights off unless you are actually doing things in the back yard? Like I said, I don't think you are doing it intentionally, but if you could keep them off unless you are using them, it would mean a great deal to me."
She said she understood, and since then, the lights are only on when they are out there, which isn't that often. And even if I am out there and the lights come on, I have no beef.
The point of my long tale is, you might be able to talk to them without having to call the police every time. If you can find some way, any way to make a connection with them, bring them a boatload of steaks for one of their parties, that kind of thing, you might find a way.
It has been my experience in life that having disagreeable neighbors is one of the most corrosive and annoying things there is. Try to connect, which I know won't be easy, but heck. I would give it a try, as hard as it is.
Good luck, fwdude.
