I agree about that landscape. The state is not as flat as people think it is either. Very scenic. I worked the southwest corner of the state years ago and always loved topping a local high spot. We were surveying and out there we could set a flag a half mile away and sight off of that easily with plane table and alidade or theodolite. The atmospheric distortion would get you on a humid day or if you were shooting across a wheat field with all the transpiration but otherwise it was clear with minimal shimmer.
