What is harrison south-dakota?

As an AI language model, I don't have any information about a place called "Harrison" in South Dakota since no town or city called Harrison can be found in South Dakota. However, South Dakota has many other cities and towns such as Aberdeen, Rapid City, Sioux Falls, Pierre, Deadwood, etc., each with its own unique characteristics, attractions, and communities. If you have a specific town or city in mind, I'll try to provide you with more information.
