As I mentioned in my recent Investing in Georgia post, the "Empire State of the South" has a diverse industrial output that ranges from peaches and peanuts to aircraft manufacturing and tourism (much of which is taking a hit from this year's severe drought in the South).

Georgia is home to such corporate giants as Coca-Cola Co. (NYSE: KO), The Home Depot Inc. (NYSE: HD), and United Parcel Service (NYSE: UPS), and the state also has just been named the second-best U.S. state in which to do business by Site Selection magazine. Georgia has been in the top four on that list for the past four years.

The Peach State is also home to Acuity Brands Inc. (NYSE: AYI) and Global Payments Inc. (NYSE: GPN), which I examined previously, as well as RPC Inc. (NYSE: RES) and Radiant Systems Inc. (NASDAQ: RADS), covered here. RPC and Radiant both made Fortune's 2007 list of the 100 fastest growing companies in U.S. It was Radiant's first time on that list, and Radiant has also been named one of the fastest growing tech companies in Georgia for the third straight year.
