I am sure you are surprised to know that there is a Corn Palace. I had seen it mentioned when I was doing my trip planning but did not think much of it. Well, we had a little time to kill before meeting up with my family so when we saw the signs, we pulled over and got more than we expected.
That is made from corn cobs, the tassels at the top of corn, and wheat.
Yes, that is Willie Nelson. (Sorry for the angle we were up on an observations deck and it was hard to get a good picture.)
Inside the palace was a little children's museum all about corn and the girls were in heaven. That cash register actually worked - as in you scanned it and on the screen appeared what the item was with a price next to it.
We learned a a few things about corn (like popcorn happens after the substance inside is heated to a liquified goo and then it explodes out and is instantly cooled into the puffy white popcorn we love) and bought some popcorn for the road of course.
They were beginning the process of taking down these designs hence the truck. They replace them every August.
