phpRcoEkZPM.jpgFollowing the Madison Square Park Conservancy putting up some tree huts, NBC has built "a giant treehouse at the corner of Broadway and 51st Street to tubthump the Oct. 17 debut of its drama series Crusoe," Variety reports. This one will is a replica of where Robinson Crusoe lives in the network's adaptation of the Daniel Defoe novel. Can't make it to the 30 Rock area? It's all online, with 24-hour webcam action. But this thing would be a lot cooler if it were actually, you know, in a tree. Either way, it'll be around til Friday, with a hired-actor playing the part of Crusoe.
