If you want breathtaking landscapes, Kansas is the last place in North America to look. However, there are things worth seeing. I recently spent a couple hours at the Cosmosphere in Hutchinson, which has an impressive collection of aerospace memorabilia, including a SR-71 Blackbird in the lobby.
Various historical sound recordings play continuously at the exhibits (JFK had a rather annoying voice). I didn’t hear Tom Lehrer’s tribute to Wernher von Braun, though.
There’s lots more there. I’ll be making more trips.
