East part flat and farmland, west part more hilly with ranch land and lot of Indian Reservations-the Black Hills, Badlands, etc. The Missouri runs through it and there is some great fishing AND pheasant hunting there.
Winters are REALLY cold and like all plains states, blizzards-the snow goes sideways resulting in whiteouts.
Find a Hutterite community and get some land aside them. Make friends with them and all that. You’ll never starve. Need to know German though.
I think most/all of the Hutterites can speak English to outsiders. The German they speak is a Low German dialect, not the standard High German taught in schools.
