Yesterday marked the 21st anniversary of Alabama’s Robert Trent Jones Golf Trail, which recently recorded its 10 millionth round of golf. What began as a concept to enhance the state’s image and boost its lowly public golf inventory has mushroomed to 26 courses at 11 sites throughout the state. Golf may have its naysayers, but before 1992, vacationing players only drove through Alabama on their way to Florida, and before the Trail’s debut, Alabama’s tourism revenues were under $2 billion. Last year, tourism revenues exceeded $10.6 billion, and the Golf Trail—often copied but never duplicated—was the state's top attraction. To celebrate the Trail’s success, golfers can tee it up on the Trail for $21 (cart extra; some restrictions apply) on the 21st day of each month for the rest of 2013. By the way, the photo above is from the Backbreaker Nine at Silver Lakes, located between Aniston and Gadsden: There's much more like that throughout the state.
