Between spring 2016 and that of 2018, Antonio Rovaldi walked around the margins of New York, tracing the perimeters of all five boroughs that make up the city. It’s in these border zones that the concrete jungle thins out, suddenly giving way to nature once more.

But one thing would remain unchanged: my constant rethinking over where I come from, where I’m headed and at what speed.
