Chris O'Toole writes, "Several years ago, Pittsburgh writer David Bear surveyed the tallest building in town and had an epiphany. He realized that the one-acre roof on top of Downtown's 841-foot-tall U.S. Steel Tower was the highest flat space on any building on earth. So why not make it into the coolest park in the world?
"A similar tall building in Chicago, the Wills Tower, has generated significant interest and revenues from its new Skydeck. But unlike that indoor space, High Point Park would let visitors 'wander around and have a picnic,' Bear says."
