Do you think you know everything there is to know about Savannah? Maybe you’re a local who knows all of the city’s crooks and crannies but have glossed over places and particulars you pass by all the time? Or perhaps you’re a visitor ready to explore “The Hostess City of the South” but have no idea where to begin? Savannah author Christopher Berinato may have some surprises for you. This week Leigh and P. T. chat with Chris about the secrets he discovered for his new guidebook — not just the weird, the wonderful, and the obscure, but also people, places, and phenomena deserving of some additional information. There’s something here for visitors and residents alike.
