Pennsylvania. I have had issues with a neighbor always on my driveway to access his garden and their refusal to move out of the way so I back car out of drive to go to work, shopping etc. This has gotten better but he is still mowing about 8 feet into my backyard. My wife and I have both asked him to stop as he sets deck really low and scalps grass. As a side note our yards are too small really for the riding mower he uses, everyone but him can easily use push mower in 40 mibutes. He said to me yesterday he will not stop as I am just making his life difficult and that I am selfish. How do I approach, I have tried to be nice for months?
