I hope you can find reasonable airfare. I've driven that route on the way to Scribner and Earlville. Omaha is a longer drive than Topeka, the scenery resembles Kansas, and there seems to be a lot more large hog and cattle ranches close to I-76 and I-80 than there are on I-70...if the wind is blowing the wrong way, the atmosphere can be pretty rude.
