I don't know how you area is, but we have a neighbor that did that for long time along our entire property line on their side. The rest of our property is fenced and the property line is on the other side of the drive and their drive goes along side of ours about 40 feet away. There was no reason to put up fencing, so we had some old farm fencing posts and put them up along the driveway. It gives it a "farmy" look (we have about 3 acres, not a farm) and it keeps them mowing on their own side. They didn't know why we did it but said they liked it. It keeps the piece and you can have your lawn back!
