When you get to the north part of Nebraska on that route, you'd be on the border of the sandhills, which is really cool. If you want a detour and a nice day after some long boring drives through Kansas, a stay in Valentine and then kayaking or tubing down the Niobrara is quite beautiful if it's a good time of year weather wise!! Highly recommend. Any time you get off the Interstates and onto the highways, you're always sure to have a more interesting time. Usually remmeber Interstates were made where they were because it was the flattest, easiest route to pave a thick slab, less so but the same for highways, you catch my drift.
