It would take me 8 to 9 hours but would be tempting.
That seems like a long time, but I guess you dont have a straight shot.
Best route (at least when I was stationed in Omaha), I55 to StL. Then the Interstate over to KC.
About 150 to StL. And then If I remember about 250 to KC from there.
Ok, Maybe it was more like 6 hours. It was about 9 hours to Omaha.
