Thank you all for the replys and the time it took to read. So the fence idea just isn't going to happen. It would really get him going even if we did it and most of the issues we have would not be stopped by a fence. Since it is a duplex we see each other out front and there is wall banging and drum playing on the inside. The people over on the other side who are in a different duplex actually put up a fence to protect their daughter from the bikes. Tim did not like that at all and said "what if one of my boys hits it, Tommy just wiped out in those bushes last week" other neighbor said "thats my point, thats where my kid plays." Fence builders told other neighbor "I see why your putting up the fence" Tim told them to make sure they didn't get any dirt on his yard. His whole yard is dirt!
Yes the police have been notified numerus times of the dirt bikes by other neighbors of small children trying to sleep. They say if its before dark they can't do anything. I think they just don't want to deal. My big regret was underestimating how crazy he is and not starting with police reports immediately but the truck incident was reported. They said they couldn't do anything but if we wanted could take him to civil court, which really wouldn't do anything. We are going to report the breaking of the beer bottle but DH hasn't gone yet. Even the incident across the street they didn't seem to care thats why he is taking him to civil court.
Air conditioning thing I think is simply a control issue. Can't think of anything else
Dbrother did live here for about 3 years prior to us. He never had problems because he was 30 with no family with him, didn't use the yard and basically Tim just did what he wanted and DB was fine with that. Also Tim sold that side to DB. To be clear at this time DB owns my half, Tim owns his half. So I think Tim considered him his tenant and didn't have a problem since he chose DB not us.
Most of the stuff this guy does I don't even mention because it just borders on legal. Nothing you can really do but just know he's a jerk. Last snow storm we had prior to the beer bottle incident. DH was shoveling end of driveway. Tim goes past our driveway with his plow to plow other neighbor. He goes to turn the spitter, but stops and sprays DH with it. Jerk! but illegal no, and if the cops don't care about the other stuff they certainly won't about that. Our dream is that DB rents to a cop after we leave.
