Isolation is another theme in the story. References to the physical isolation of Savannah and characters' isolation from each other consistently influence the tone of the book. The physical locality of Savannah secludes it from the rest of Georgia. It is difficult to reach the city by plane or train, and the description of the drive in to the city only emphasizes its contrast with the rest of the world. It is described as seeming like a different world, with different terrain and a distinguishably new feeling in the air. Some Savannah residents such as Mary Harty seem proud of this remoteness, others, like Luther Driggers, take on a depressed and submissive nature, when acknowledging Savannah's detachment from the world. However, all admit that it is its own unique world of customs and stability.
