Avenue of the Stars had the netting and zip lines back a few years ago. That's the only thing I can think of other than the podiums and Wavy Tube Man which hopefully would not be included in the idea of things above head.
I really am eager to see this zone. As of now nothing has impressed me except the giant face candles. I really do hope this is not a cluster being that it's next to Dusk and along the path of the other SS. I do believe as a house it would have killed.
