Louisiana has used the Waffle House Index before, as have other hurricane prone states. Which is actually where most Waffle House locations can be found.
For reasons we'd rather not discuss here, it's 4 AM and you're driving to Ellijay. Cold rain turning to snow. And you're hungry. Everything's closed. Then you spot the familiar yellow sign. You know 'em. You love 'em. It's a Waffle House. Turn signal, brake lights. Thanksgiving is just days away. But if you can't wait for turkey and all the fixin's, and you're craving some home cooking good news! If you're presently in the Southeastern USA, there's a Waffle House or two at the next intersection. What time is it? It doesn't matter. Each and every location is open 24/7, 365 days.
