Yes, our clique called all flavors of carbonated bottled beverages by many names, Coke, pop, cola pop, soda pop, soft drink, cold dope and some others, they were all interchangeable and everyone knew that you were speaking a language they could interpret.
I was squirrel hunting one day on property that was taken into the state DNR lands, it was an area that was bypassed by the federal Interstate Highway system. There was the foundation of a small family run grocery store that had been demolished, within the ruins of the foundation, I recovered a "pop" bottle, clear glass, that was labeled Jeff Cola.
That sparked my interest and I proceeded to research on the www, that research turned up a local bottling company within the city where I work. Farther research was provided by a customer of the auto repair shop where I was employed. The fellow was a resident of Jeffersonville, IN from the 1920's through WWII and into the 21st century and provided more information about Jeff Bottling Co.
You will be surprised at how many local beer breweries had their bottling processes intertwined with "soft drinks".
