The author of "A Voyage Long and Strange" recommends the Etowah Indian Mounds in Cartersville, Ga.
"While researching A Voyage Long and Strange, I did weird things in remote places. One of my most exotic stops was just north of Atlanta. The Etowah Indian Mounds are a time capsule of a civilization that few know existed. Centuries before Columbus, local Native Americans built earthen domes and crafted artwork from sharks' teeth and marble--all of which is on display in a 54-acre site next to a trailer park in Cartersville, Ga."
