I just heard last week about another in SD that supposedly got backed over by some large farm equipment. Since the person did it themselves the insurance companies for the farm and the auto are fighting one another on who pays for it. Apparently they didn't have a complete coverage for everything on the farm from one company.
The story he is going with is that it was in his driveway but the parking brake wasn't set and it rolled down the driveway behind the equipment. He didn't see it when he was backing up the equipment (earth moving scrapers). He said he didn't even notice backing over the car and I don't imagine so. There were 2 of those large scrapers hooked up to a large 4WD tractor.
