In February 1970 the editors of American Heritage published “A Wrecker’s Dozen,” by David McCullough. It predicted the destruction of thirteen American buildings and lamented the lack of a widespread conservation ethic in the United States. A while ago G. W.Leaworthy of Titusville, Florida, wrote to us, asking what had happened to the doomed buildings. We decided to find out, and we’re happy to report the news is mostly good.
