Pierre may be the capital of South Dakota, but Sioux Falls has more Century Club Companies. All told, the state has at least 19 businesses 100 years or older and all of them are privately owned. I could use a little more information for some of them and - as always - if you know of a company that has been in continuous, independent operation for 100 years or more (whether in South Dakota or elsewhere) please leave a comment.
