Aerialist Erin Blaire, 33, performs a hair hanging trick for a photographer while hanging from a metal bar on a subway platform on March 14, 2023 in New York City. Erin Blaire, originally from Vermont, has lived in New York City for eight years and has been performing her aerial hair routine for the last three. The origin of hair hanging is believed to have originated in China, according to reports, and is a closely guarded circus trick passed from mentor to mentee. Although it is possible to find the technique and secrets online it is most-likely not how professional performers learned the skillset, and not how Blaire did either.

A racoon jumps over a fence in almost deserted Central Park in Manhattan on April 16, 2020 in New York City. Gone are the softball games, horse-drawn carriages and hordes of tourists. In their place, pronounced birdsong, solitary walks and renewed appreciation for Central Park's beauty during New York's coronavirus lockdown. The 843-acre (341-hectare) park – arguably the world's most famous urban green space – normally bustles with human activity as winter turns to spring, but this year due to Covid-19 it's the wildlife that is coming out to play.
