The Hallett Nature Sanctuary in Central Park is a world within a world within a world. The outer world of NYC blasts and blares and screams and scrapes. The neighborhood surrounding that corner of the park is an obscenity of wealth and poverty. Within that world is Central Park – the lungs of the city and a literal oasis of calm in a city that doesn’t sleep or even relax. Within the park, the nature sanctuary ratchets the stress of the city down a few extra notches. The air is soft and heavy, redolent of a shrine. I found this fence and its shadow waiting for me there.
