I visited Chicago during Independence Day weekend. It was my first time in Chicago, and I enjoyed seeing the major sites in Chicago, as well as the Taste of Chicago. Four things are associated with Chicago: revolving doors, fireworks, pizza, and skyscrapers.
I stayed in the Hyatt Regency in downtown Chicago, and had a room with a nice view of the Chicago River.
Pictures for each place I visited:
Sears Tower, currently the tallest building in the United States. It had been the world's tallest building until the openings of the Taipei 101 and a tower in Dubai.
Museum of Science and Industry, including a Green House tour which is a house designed to be environmentally friendly.
John Hancock Center, the third tallest building in Chicago and close to Lake Michigan.
Fireworks at Navy Pier, which I saw from the John Hancock Center observatory.
United Center
Boat tour around Lake Michigan with views of the Chicago skyline.
