See this...Really tall building right? It's got some new name...in my world, it is...was...and always will be The Sears Tower.
Anyway, they are building this for viewing...There will be four glass bottom "ledges" built onto the building. The retractable boxes will extend 4.3 feet out from the side of the building at 1,353 feet above street level.
It opens in June...Ummmm....I want to pass out just thinking about it:P
Would you step out on The Ledge?
