Goodland: Sunflower City!
Goodland calls itself "the Sunflower Capital of Kansas." It's a good slogan, and there are a lot of opportunities for developing the theme. (Otherwise, Goodland is probably best known as the last Kansas town on I-70 before you cross into Colorado.)
A schoolteacher here conceived the idea of installing a large easel and giant "canvas" with Vincent Van Gogh's "Sunflowers" resting on it. It's not particularly visable from the highway, though, unless you're looking for it. And right now there aren't any real tourist facilities associated with the Van Gogh, just a parking lot close to a Pizza Hut. It might make a great place for a "Museum of Sunflowers," or even a hall with exhibits displaying some of the things that you can do with sunflowers.
Just an idea. . .
