The Turner Katy Trail Shelter in Tebbetts is a good place to stop for a nite, and the Katy goes right thru a campground Called Coopers Landing (and I mean right Thru,you won't miss it!) about 15 miles east of Colombia Mo that is one of the BEST local hangouts in Mo...Live music,Bar,Camping (10 bucks a nite) a Great place to meet some of the local folk.
Booneville has a really good (but kinda spendy) coffee shop Trailside
Rocheport is a tourist trap,But the Rocheport Tunnel at MM178.9 is cool!
In Sedalia The Katy takes a road detour thru town(Follow arrows painted on pavement)
Check out the MKT explosives bunker at MM177.5
