Manhattan's lots of fun. It's a cultural, financial and trade center, but not an industrial one, I guess. I get there occasionally. Have been in upstate NY off and on recently too, as my daughter went to college there. I really like upstate NY, it's beautiful and the people are friendly, but the place seems on the decline to some extent. Downtown Schenectady looked like a ghost town last I was there, but some downtowns look that way just because the centers of commerce moved elsewhere. But I remember when most small towns in upstate NY had a factory. I have the impression that many of those are now closed.
Beautiful Mohawk Power building, Syracuse. Art Deco, 1932. Miami Beach doesn't have anything close.
