What are you NUTS?

This is completely crazy! The Sears Tower in Chicago has built glass ledges for those who aren't afraid of heights: "�these new glass enclosures that extend 4.3 feet beyond the side of the building. Beneath peoples� feet lies the sprawling Illinois city - 103 storeys, or 1,353 feet, below. Just an inch-and-a-half of glass separates the visitor from the street underneath. The attraction is due to open in June."

Would you dare? I'm not sure I could....
