Kansas & Nebraska are probably two of the only states that, on a clear day, you can see from border to border!!
I exaggerate, but as has already been noted, it seems only true Kansans(and probably Huskers, too) can appreciate the long, flat, rolling praries. If you're riding on the Interstates, I'd say just bypass them completely. There's nothing here to see, folks. . .
On the other hand, many of the rides we take out of Topeka take some of the back roads, state highways and the like. Many of them, while not heavily travelled, are fairly decent roads, and not many of them are straight, either. No radical twistys like you see in other states, but enough turns to keep your attention.
And that hill out by Wilson? It's just a speed bump, no hills in western Kansas until you get closer to Colorado!
And on a final note: I don't know what the roads are like in the rest of the state, but the roads in and around Topeka are hideous!!!! There are some potholes in some of the streets here that I am convinced would throw a rider right straight through his/her windshield!! There are a couple of road holes I've seen that I think I could hide a Sportster in. . . .
I'm kinda glad my bike is still in storage, I'm not sure I could ride between all of the holes and stay up on two!
But, if you do come through Kansas, better give us a shout!!!
