I went on a trip to Chicago to meet my cousins .I went to the Willis [sears] Tower in Chicago. It’s 110 stories tall,the only way to get to the top is by elevator,the elevator goes 40 Miles per hour. There’s something called skydeck which is a glass ledge attached to the building,from the ledge you can see most of Chicago. Skydeck is on the 103rd floor. You can see Willis tower from Michigan,Illinois,Indiana,and Wiconsin. It’s the tallest building in the U.S.A.
