Missouri ride

June 6th myself and a small group of my buddies are headed to Springfield to see one of my buddies Nam Marine buds,heading out thru Indiana and Illinois on rt 50,then down 1 then over to 3 then down to Cape Girardeau then down to 60,then 60 to Springfield this will be my first time in missouri,any places that we should see or stay away from in Missouri,then we will be heading down to Arkansas thru some of the Ozarks,then Memphis and back thru Tenn and KY taking a week.In no hurry going to try and stay of super slabs as much as possible,if there is a better route than 60 i am open for ideas.
