Is the Double Cola/Ski sold in Danville in glass or cans?
At the Food City in Pulaski, Virginia ( a few miles off I-81) I found the following.
Ale 81, Dads in glass; plastic and cans, Red Rock cola in glass, Frostie in glass; plastic and cans, Dr Enuff (first time seen that far north) and a 12 pack container of vintage sodas in glass (probably the same as Old Country Buffet sells).
I did find 2 liter bottles of Big Red and Big Red Zero at the Food Country in Fort Chiswell.
Nehi Peach was also seen in both plastic and glass at various stops.
