The Aon Center is already impossibly tall. Not sure I've you've ever been to the America Club on the top floor but you can pretty much see the entire Chicagoland area from up there. Yes, it's just like the skydeck at the Willis Tower and yes, this is all I think about. Now take that and look at the thumbnail below. You're in a secluded box and hangs from the side of the building. Just saying that is giving me flashbacks to several Spiderman movies. Only problem, he's a fictional character and if anything goes wrong we're done. It's going to take me A LOT of money and alcohol to get on that thing. Tell me what it's like when you go though!
