I just left New York after 12 years. One day, while I still lived there, I decided to see if there was anywhere I could be in Manhattan without seeing another human being in my field of vision. It took me several weeks of exploring possibilities, none of which were successful. Even Central Park didn't work, there was always someone wandering by, no matter how remote the spot.
I finally found the only spot where I could be for 30 minutes at a time, in total isolation. The New York Marble Cemetery on 2nd Avenue, in the East Village. It's a small patch of land, hidden down a narrow alleyway, behind a gate, open to the public just one day a month. It looks like nothing but a lawn surrounded by stone walls, because there are no headstones. It became my favorite day of the month, that one Sunday when I could go sit on a lawn in silence and solitude.
