I have 7.5 acres of land and about .5 acres is a narrow split between 2 neighbors, apparently they have used it for who knows what ( a lot of trash is there etc) what is the best way to utilize the land/ create a privacy screen so they cannot use it. I met one of them and the guy is a total douche, and tried to argue that he has a right to the land which he doesn’t. The piece of land is 50ft by 650 ish ft. Any advice is welcome.
