Chesterman Coca-Cola has one production facility in Sioux City, IA. They have sales centers in Aurelia, IA, Kearney, NE, MaComb, IL, Sioux Falls, SD, Yankton, SD, Mitchell, SD, Watertown, SD, Huron, SD, & Pierre, SD. I also remember that Black Hills Coca-Cola in Rapid City used to buy cans from them. I have seen Diet Pibb & Diet Mello produced by them.
The last time around 1992 when I was in Rapid City the only thing I believe they produced was 10oz Returnable Bottles. They had Coke, Diet Coke, Sprite, Mello Yello, and a few others. I believe the other stuff came from Chesterman.
