Hwy 36 across Kansas

I have not traveled hwy 36 west of 135/81 but have drove from 81 going East. East it is rolling hills small towns and farmland. Don't know what your interested in.

Campgrounds at Wilson, Milford and Tuttle creek reservoirs or nice to spend time at but are along I-70. Along with the Eisenhower Museum and Walter Chrysler's boyhood home. Another neat thing is Atomic Annie a cannon that would launch a atom bomb, closed for now freadom park FT Riley.

There is a guide Ohio to CO US 36 guide.Com that have more information.

You can also go to hwy 36 Trip Advisor web site for more information.

Personally I prefer US 36 over I-70.
As CloudDriver mentioned Prairie Dog SP is a nice stop.
North of Lebanon KS is the geographic center of the lower 48 states. Nice picnic area but that's about it.
Near Republic KS is the Pawnee Indian Museum which is very nice.
At Maryville KS is a Pony Express Museum but I don't know if it's open. It was closed due to covid.

I found Scott county lake/campground to be sort of interesting. drive up to it over flat country and the lake drops down away. Chalk pyramids interesting and then of course there is the world's largest ball of twine and I think largest hand dug well is also in KS. I'd probably take the interstate across however to avoid local stop and go and manure spreaders on the highway.
IIRC on one raffle/drawing second prize was two weeks in KS. first prize was one week.
bumpy

If you do not like tourists Kansas is a good place to live.

The wife says there are only 2 good ways to see Kansas... at night or from 36,000’. I use I-70 so it only takes a day to put it behind me. The excitement used to be which side of the highway the tumble weed was on... not as much of it any more. Hopefully you’ll have a tailwind so it takes less time.

We have used Prairie Dog State Park as an overnight when crossing Kansas on route 36. Nice campground on a lake with a Prairie Dog town and wild Turkeys. We were there in May.
