If given a list of 8 top 10 things all Americans should see (in the US) a disparate list would be formed.  Nature?  Culture?  Many things, here's a list from CNN starting with ... the Sears Tower?

It's fitting that the country's tallest building, the Sears Tower (we haven't come to terms with the new name either), is in the same city that built the first skyscraper, the Home Insurance Building, demolished in 1931. Chicago's innovation sparked a worldwide race that continues to redefine city skylines from London to Dubai to Taipei. There's simply no better way to experience those early architects' remarkable vision than to stand on The Ledge at Skydeck Chicago, a transparent observation box that suspends you 1,353 feet above street level, on a wisp of glass just one and a half inches thick.
