I wondered if you guys cold help me with a trip I am wanting to plan. Long story short I want to float the Missouri river from Yankton South Dakota to Kansas City. I live in KC. I have the Corp maps but they end at the point the Nav channel ends above South Sioux City. So I am looking for some maps above that point to Yankton. Thanks for whatever help you all can give and stay warm. Also if you have other info that you think would help feel free to pitch it in and I will update when I get the trip set up. Thanks again.
