I only know of a few having lived in southwest kansas ; There is the (at least when I was there) the worlds largest beef slaughter house in Kearny County which back then was Iowa Beef Processors and now I believe Tysons' owns it. In the same county in the town of Holcomb back in November of 1959 the murder of the Herbert Clutter family. Dodge City is there where they used to drive the cattle to back in the "Horse and Buggy day" and the railroad that made it easier to transport cattle back east. The Arkansas River which flows into the Mississippi.
The most ironic thing though is that someone wanted to know this and asked via a computer when the most info available is through one.
