I drove across Kansas on a trip almost around the US (got cut short in 3 car accident) and it was mile after mile after mile of nothing but fields, as far as the eye could see. Then out of nowhere it seemed, I would get to the top of a small rise, and there in the valley would be a smal, town. It was quite an experience to see all that land with. Nothing on it. I am used to farmland where many acres of crops were, but not on the scale i witnessed out west.
Foreigners seeing the US Midwest are frequently incredulous.
I once took a professor from India on a tour of part of the Mississippi River. When we visited a lock and dam observation room, he understood what those numbers regarding how much grain passed through the lock meant. He could hardly believe it.
