Banking. All banks require a valid Social Security number prior to opening any form of account, including checking, savings, certificates of deposit, credit cards, vehicle loans and mortgages. They use this for exclusive identification purposes, as no two people have the same number.
The first official Christmas tree in the city of Chicago was installed in 1913 in Grant Park and lit on Christmas Eve by then-mayor Carter Harrison. This first tree was a 35-foot (11 m) tall spruce tree.
The city of Chicago is known for many things. It is known as The Windy City more for its politics than for its weather. It is well known as the home for many of the works of architect Frank Lloyd Wright. It is the home of the Merchandise Mart which is the only building in Chicago (and maybe the country) that has its own zip code (60654). It is known as the home of one of the tallest skyscrapers in the world, the Sears Tower (or, as some now call it, the Willis Tower). It is known for the Great Chicago Fire which is fabled to have been started by a cow kicking over a kerosene lantern, but which became the civic lesson from which many current city ordinances were enacted.
