Amtrak River Runner Route....KC to St Louis. It doesn't go to Clinton, but it stops in Lees Summit. You could bike the Rock Island Trail down to the Katy. Or up. Note: The Rock Island is not 100% complete and requires a nine mile ride on mostly quiet streets and highways. There is a shoulder on the three mile stretch of 150 Highway.
