I lived in wichita ~35 years ago and have fond memories of Cowtown, dilapidated farms and beautiful old architecture.
I'm planning a trip there end of next month with my two DD (12yo and 9yo) and my brother.
We are visiting family but would also like to visit "unique local cultural or historical sites." We'll rent a car and dont mind driving all over. We will be there from Tuesday morning departing Saturday midnight via Amtrak.
