Anyone ever been in the Sears Tower?

Willis Tower, Sears Tower, whatever. It will always be the Sears Tower to me. Anyways, has anyone ever been in the Sears Tower-aka just the tallest building in the United States (yeeeaaaa buddy)- in Chicago? It's kinda weird that I haven't because I live like an hour away. If you have, what is it like? I'm kind of afraid of heights, but I really want to go in it (I just watched Ferris Bueller last night haha). Ty guys!! :)

Take the video tour via YouTube. Promise you won't fall off. :-)
