The old New York Pavilion in Flushing Meadows-Corona Park, which has been allowed to rust and fall apart for 47 years, reminds me of the various Time Machine movies in which H.G. Wells, sitting in his time machine watching the years go by, sees Man’s great projects rise, prosper and then deteriorate over the centuries.
