[font color=\'#000000\']I visited the Tallgrass Prairie National Preserve briefly in the September 2002. http://pathfinder.smugmug.com/gallery/121083/1/4358286
http://pathfinder.smugmug.com/photos/4488631-M.jpg There is a barn with displays there and some outbuildings and ...prairie. I am not aware of hours - but the prarie is visible from the highway so should not be a problem. The Preserve seems pretty low key - there was a Ranger in the barn that day, and he seemed to want some company to talk to.
A nice place to visit, but pretty low key.[/font]
