There are No Boring Places
Welcome aboard the RoadTrip America Forums!
That is one of the guiding principles here at RoadTrip America, and certainly applies to this stretch of road. The direct route (I-35, US-75) would be a full day's drive (465 mi), but for a few more miles you can travel almost the entire way on scenic and historic roads, starting by heading northeast through Oklahoma on old US-66. You then have your choice of a couple of places to turn north for the run through Kansas. US-169 and US-59 are marked as scenic in my Rand McNally atlas, while alternatively, you can continue to US-69, the Frontier Military Scenic Byway. Both will set you up to be in Kansas City around dinner time for some great barbecue.

Watch Out for College World Series
Omaha annually hosts the College World Series in June. We found out the hard way that finding a room is next to impossible. We did find a Motel 6 with one room that they wanted $100 for. We ended up driving to Des Moines and got the last room at a more reasonable Motel 6.
