It's not that I doubted? It's that I figured such a creation couldn't have emerged fully grown from the head of Zeus. So I checked my go-to "I know fuckall about the South" reference Garden & Gun, which has exactly one hot dog recipe which notably (1) is two recipes (2) neither of which have hot dogs in them, despite (3) the food stylist's insistence and (4) is pinned on Appalachia, not Georgia anyway. Apropos of nothing,
and the Sterling Drive-In in Welch, West Virginia, makes a deep-fried sub with chicken salad, cranberry sauce, and bacon as its filling. Really.
The Sterling Drive-In has seven yelp reviews, perhaps because Welch is a hamlet of under 3,000 people that could possibly be construed as being on the road between Lexington and Roanoke if you wanted to get there very slowly.
Having failed utterly I decided to google "Georgia 'hot dog'" which did in fact generate ample photographic evidence that such a creation has been made multiple times, albeit none that it has been eaten.
Apparently the blame rests at the feet of the Dinglewood Pharmacy in Columbus, GA.
