Book excerpt: For years, veteran Atlanta Journal-Constitution columnist Charles Salter roamed the state in his 1975 Chevy station wagon in search of the most offbeat characters to appear in his celebrated column, "The Georgia Rambler." From tall tales of the Okefenokee Swamp, to treasure hunters of Duluth and ex-moonshiners of North Georgia, Salter's stories are as eclectic and extraordinary as the people he interviewed. Along the way, he discovered the alleged original recipe for Coca-Cola in the pages of an old pharmacist's book, a find that inspired an episode of award-winning radio show This American Life. Read these remarkable stories and more in this never-before-published compilation of the best of "The Georgia Rambler."
