Squash is often considered the sport of prep schools and Ivy League colleges, but four squash enthusiasts are changing that, one court at a time. The NYC Parks Commissioner Mitchell J. Silver officially opened the first-of-its-kind in the world outdoor squash court at Hamilton Fish Park on the Lower East Side. This amazingly cool court looks more like an Apple Store glass cube than a fitness facility. Even cooler, it’s funded by the nonprofit Public Squash and is free to the public and will offer free clinics throughout the summer.
