The ugliest, most ill-conceived physical addition to sports scenery was the construction, a few years ago, of the Arthur Ashe tennis stadium at the U.S. Open. Typical U.S. supersize. We'll be bigger than everyone else, so there.
Alas, in the upper reaches of this charmless behemoth you need a GPS to find the players somewhere down there at sea level. Worse, should it rain, which it has a wont to do in New York, there are no players on the court and you get wet.
