Western Hemisphere's Tallest

It used to be the World’s tallest, then the Petronas Towers got the title based on a decoration, now there’s an actual taller building in Taipei, the Taipei 101, so the Sears Tower is just the tallest in the western hemisphere.
The Sears Tower still boasts the world’s tallest antennae!
My step-daughter’s in town so we went downtown on Thursday. Yesterday we went to Woodfield Mall and today we’re going to Mitsuwa, The Mall of Japan. My step-daughter spent the last school year in Japan and hopes to return there after her graduation in May.
