Red Baron BBQ?
The man on the right is Anna’s grandfather Paul E Foster (1895-1936). They lived in the Alpharetta, Cumming, Roswell area. This is a picture Anna's mother donated to the "Vanishing Georgia" Project.
The guy on the left has a Crabapple uniform on. Crabapple is also a little community in the area. You may recognize the name from a lot of Celestine Sibley’s books. Crabapple was her adopted community.
Also, there was a barbecue place in Crabapple with an old airplane’s tail sticking out the roof. I think the name of it was “Red’s BBQ.” It might still be there, we have not been there in years.
