When I think of Chicago I think of the Sears Tower and how windy it is there.
My first visit to Chicago was when I went for Navy boot camp in 2000. After two months of training I just wanted to get out and explore the city. My first stop was the Sears Tower. It was and still is the biggest building if I've ever seen, been inside, and looked out of.
This is why I decided to feature the massive marvel in this design.
