The clean air offers me a clear view of every skyrise for several blocks, and I see with my own eyes what I’ve only witnessed in videos: the first great American attempt at sustainable urbanism. Soaring thousand-foot skyscrapers boast foliage on every terrace, like giant trunks of steel wrapped in vibrant green moss.
