The High Line is set to open on some closely-guarded secret date (though we hear it's around June 15th), and until then, it's the A list, the rich, and Kevin Bacon only! Curbed has some shots up provided by an insider at a special event that took place on the Line last night, and included guests like Martha Stewart, Barry Diller and Diane von Furstenberg. For the rest of us non-celebs, we'll have to be content with these various spy cam shots, and maybe this recent interview with the founders of Friends of the High Line, who teamed up all those years ago to save and re-purpose the defunct elevated train line.
