A big attraction along I-90 is the Corn Palace. It is not very far from the highway and so worth the short trip. The palace is an auditorium where they hold events and things like basketball games. The difference is that it is decorated with corn cobs and parts of corn plants. It is corny art, as you can see from the picture.
As you get toward the center of South Dakota, the land gets flatter and more barren. This is the short grass prairie where the pioneers had to make houses out of sod, since there was no wood. You can see below the great emptiness.
My pictures were taken near the Sinclair station. I liked the dinosaur when I was a kid. Below is an interesting sign. I wouldn’t think they would need to worry very much about parking.
