This gravity hill is located a few blocks northwest of the Capitol building in Salt Lake City. On a road that leads down into a canyon, supposedly, gravity works against known physics. If you stop at the bottom of the hill here, they say, and put your car in neutral, the car will coast back uphill out of the canyon. There's a legend behind this one, too. Someone named Elmo is buried in the area, so the story goes, and his gravestone glows blue at midnight. It's the force of this ghostly presence that warps gravity.
