The Chiefs didn't play at Muni until 1963. Old Muni was the home of the KC Blues and Monarchs until the A's came to town in 1955. BTW, it was known as Muehlebach Field, Ruppert Stadium, and finally Blues Stadium until the A's moved in.
I think you might want to include references to the stockyards for local flavor (no pun intended). GM was king with plants in Leeds making Chevys and the former North American plant in Fairfax making Buick, Oldsmobile, and Pontiac cars, hence the nickname "The BOP".
If you're looking at 1955 or so, you'd have to include H. Roe Bartle (Chief).
Kansas residents had Minnesota Avenue for shopping unless you went "overtown", that is downtown KC, Mo.
Ethnic neighborhoods were still in fashion. Strawberry Hill had the eastern Europeans that came to work in the packing houses and it was further subdivided by country, each with it's own Catholic church. Little Italy in the North End was another.
TWA had it's corporate headquarters in Kansas City until the mid-50s.
Hope that helps.
