My great uncle once wrote that he had an impure love for cities. Though he was describing 19th century Havana, the New York City High Line is the perfect expression of the sentiment. I’d been hearing about it since it opened but hadn’t gone till last weekend. An elevated railway last used in 1980, it’s been transformed into an promenade cutting into the New York City Skyline. With nature and design in perfect balance everywhere you look, it’s a beautiful tightrope.
