Take I-70 East and get of at exit 361A (1st Ave).

Great variety of scenery everything from flat open prairie to large hills and curves. Council Grove has tons of historic places to stop and see. You will also go by the Kansas Capitol building.
Good paved roads the whole way. They were doing some work between Newton and Cassoday but the road was still good. Great curves on K-4.
Plenty of places for fuel and food. Great little BBQ place on K-4 by Wabaunsee Lake. You may want to take camping gear and do a 2 day trip out of it. There are lots of lakes and state parks along the route.
