Hudson Yards still has a trick or two up its sleeve. On Wednesday, the development in Manhattan's far West side, marked by shiny high-rise buildings and the Vessel, a curiously-shaped landmark with a lot of stairs, presents a new offering. One hundred floors up, and over 1,100 feet in the air, Edge has built-in bragging rights: It is, after all, the highest outdoor observation deck in the Western Hemisphere. Take that One World Observatory and Willis Tower. The outdoor space edges (get it?) out into Manhattan, approximately 80 feet, with head-spinning 360-degree views of the city's skyline and beyond.
