Scaffolding collapse at 915 Broadway and 21st Street! Or actually near-collapse! Firemen on a crane, dismantling! Block closed down! New York Observer reporters forced to take freight elevator in back of building! Take-home message: Don't take a cab down Broadway south of 23rd Street, not that you should anyway, because that is a TERRIBLE route no matter where you're going because of the way Broadway dumps out into Union Square, obviously, but it is totes particularly bad right now! UPDATE: OOH, PICTURE!
