Who can go to Chicago without looking at the infamous Sears Tower... This tower stands 1454 feet tall ( 110 stories), houses 200 foot high antennas atop, and weighs 445 million pounds ( geez I don't feel so bad.) It held the world's tallest building reputation until the late 1990s. If you've ever been on the elevator that takes you to the top, you'll never forget it. It's FAST!
