Have you visited The High Line in New York City? I haven't gotten there yet but aim to see it in person one day. In the meantime, there's PBS to take us on a visit via armchair travel!
Great Museums “Elevated Thinking” (Sat., July 19, 2014, 9:00 pm, PBS Hawaii) explores this captivating public space. Recycled from a defunct elevated railroad, High Line Park hovers 30 feet in the air and winds through 22 blocks of Manhattan.
