I just vacationed in the state in August. Nice scenery. The eastern half is agriculture and west half is ranching and has the mountains. I visited Custer, Rapid City and Chamberlain. Turns out commentator Tomi Lahren is from Rapid City. I enjoyed Custer State Park and The Badlands.
Here is more on the state:

Spent a week in Rapid City in June as a belated birthday present from my wife. We saw Mt. Rushmore, Crazy Horse Memorial (very well done but doubt it will be completed in my lifetime), Badlands, Devil’s Tower, Spearfish Canyon, Custer State Park, Sturgis (barely noticed without the crowds), and Deadwood. Scenery was great but it was the local people that impressed me the most. They were some of the most friendly and polite we have encountered in our travels. This attitude applied to many an overworked employee as there was a severe shortage of workers which forced some businesses to remain closed despite South Dakota being an “open” state. Even residents encountered in local stores had this attitude. A great state but not enough to tempt us to move from Florida.
