You Have Got To Be Kidding Me: Sears Tower Unveils Glass Balconies on 103rd Floor.

The Sears Tower opened "The Ledge" to the public today. The Ledge is a 4-foot glass balcony that's suspended 1,353 above the ground on the 103rd floor. It provides a panoramic view of Chicago, provided the walls aren't covered in accidents. Fun fact: urine spilled from the 103rd floor can break concrete on the sidewalk below. And not just if you drank a jackhammer, but it helps.

Thanks to FDSY, who isn't afraid of heights, but is afraid of towers. Weird.
