I have a next door neighbor, who takes very dim view of slight encroachment on the grass at the end of our driveway, in the past he has put up iron posts,which scrached our car. now he is parking his van right at the end of our driveway so close to the line it is almost impossible to back out in one try. is there any law about parking too close to the driveway opening? Thanks at least I have vented.
