Neighborhood: Upper East Side
From 1976 to 1984, the elevated commute across the East River from Roosevelt Island to Manhattan was the only aerial tramway in North America. Then Mississippi built one. But everyone knows New York does it better. Tourists love walking across bridges, but nothing beats the rarefied space of air travel, without the pain of booking a flight. The views of Manhattan are unparalleled, the sort of thing you'd need a rebel billionaire and a helicopter for. Instead, you can just check out the tramway.
