Annoying new neighbors

Yeah.. we have one of "those" too. Came home one day and they had torn down all the trees right through the creek which flows through the back. Dug holes in the protected marsh, it's a riperian zone. We used to get owls and all kinds of neat wildlife back there. They've since moved on. Jugs of hydraulic oil dumped over, trash bags everywhere. The bear came through and tore all their garbage around, they've just left it. Then there is the kids girlfriend who screams at the kid, every Saturday morning. And the music blaring at 3 AM on a weeknight, when everyone else has to get up for work in the morning. Oh, and the massive fires in the middle of August during the burn ban. No matter how many times you try to deal with it yourself, or call the cops & fire department, they just get worse and worse.
