I spent 24 hours and one night in Savannah, GA, and every corner felt like stepping into a storybook as fan palms swayed, giant leopard plants in every square, ornate gas lamps glowed over wrought-iron gates, and willow trees shaded peaceful parks. You can walk the whole city in a day and see a lot so that's what I did since I was only there for one night. The "grid system" plan is why it is so walkable. One of the rare, small American cities that have a European feel.
