There are a lot of benefits to living on the top floor of a building. And while some might consider living right above the Metro North rail line (that runs smack down the middle of Park Avenue) a disadvantage, that empty air gives me a pretty good western view. I get a front row seat for some mighty splendid sunsets.
Though I don't have an elaborate terrace, I do have a fire escape just outside my window. From the 'scape I get a magnificent southern view straight down Park. If you can spot the Met Life Building in the photo (in the middle), that's roughly 70 blocks away. You can also see where the rail line comes out of the ground at 96th Street. FYI, on the rich end of Park Avenue (below 96th), the train is underground and there are lovely little medians with flowers.
Ah, city life!
