This map shows the relative locations of: Marietta, GA, where Mary Phagan was born; Atlanta, GA, where the majority of the play takes place; and Milledgeville, GA, from where Leo Frank was kidnapped and taken to his lynching.
Marietta is about 20 miles from Atlanta. The journey from Marietta to Atlanta could take about 5 hours by horse-and-buggy, or 7-8 hours on foot. However, Mary Phagan's large family would likely have taken much more time to migrate to Atlanta with many people and belongings.
Milledgeville is about 89 miles from Atlanta. For Lucille to visit Leo for "All the Wasted Time" took at least 3 hours by a Ford Model T.
Milledgeville is about 106 miles from Marietta. It took the mob approximately 6 hours to drive Leo from the State Prison in Milledgeville to the site of his lynching in Marietta.
