I encourage you to check out Tallgrass Prairie National Preserve. It's about 1.5 hours northeast of Wichita. Bring good walking shoes for one of trails and make time for the 90 minute bus tour through the 10,000 acres. http://www.nps.gov/archive/tapr/home.htm
Another great resource is www.byways.org The website for the National Scenic Byways Program with maps and ideas for day trips along each route. And if you're ever in Cottonwood Falls, get a four star meal at the Grand Central Hotel where an old friend of mine is head chef.

And I had the perfect soundtrack for the drive, the Kansas vs. Kansas State football game, made even better by KU's win. Go Jayhawks!
