You can't say you've seen NYC until you've seen it from a boat. Hop on the ferry from anywhere to anywhere and you'll see what I mean. Not only will you see excellent old buildings and factories--the inner workings of the old industrial city--but you'll head out under working bridges and see the skyscrapers in all their towering glory. And once you've done it, do it again, at night.
My favorite wall in New York. The wall outside St Patrick’s old cathedral on Mulberry Street in Manhattan. It changes with the light, so beautiful. It was also in the movie “The Pope Of Greenwich Village” and that’s just plain cool.
