Thanks largely to Margaret Mitchell's classic novel Gone with the Wind, the state of Georgia has come to embody the idyllic gentility of the antebellum South. However, Georgia has long been a leader in the industrial and economic development of the southern states, so much so that it earned the nickname "Empire State of the South." Although probably best known for its Georgia peaches, peanuts, and Coca Cola, the state boasts a variety of industries, including aerospace, aircraft construction, publishing, real estate, and telecommunications. The city of Atlanta is a major railroad hub for Norfolk Southern and CSX, and is home to Hartsfield-Jackson Atlanta International Airport, widely regarded the busiest airport in the world.
