Do you have tongue twisters about South Dakota?

I don't have any pre-made tongue twisters specifically about South Dakota! But, let's create some together:

Easy:

* Say "Sioux Falls" fast three times.

* The South Dakota sun shines so bright.

Medium:

* The Black Hills bison are big and brown.

* The Badlands are bumpy, but beautiful.

Hard:

* The Spearfish Canyon scenery is spectacularly scenic.

* Three tourists took a trip to the Theodore Roosevelt National Park.

* She sells seashells by the seashore, but not in South Dakota.

Let's get creative! What aspects of South Dakota do you find interesting? We can turn them into tongue twisters.
