The High Line park in NYC is one of the places that is still relatively unknown. Sitting 20 or so feet above the ground, the park is an old railroad freight line that runs up the West Side of Manhattan from from Gansevoort Street in the Meatpacking District to West 34th Street, between 10th & 11th Avenue. Being only a short distance above the city almost eliminates the traffic noise, such that you can forget you are in the middle of a huge metropolis. Over the years as the park matures I’m sure it will be a fantastic place to take a stroll through the cool autumnal air. If you haven’t yet checked it out I would highly recommend that you do very soon!
