Left Bismark in some rain and rejoined the Interstate 94, but not for long. Turned south and followed the Missouri river until entered the Standing Rock indian reservation. Soon after I entered South Dakota. You should the countryside. Nothing specific to see but a lot of it and scenery was spectacular in its vastness. The scenes from North by northwest sorung to mind as I was driving. Even got a little fed up with all the driving. Barely made it to Rapid city South Dakota where I collapsed in a quickly erected tent. The next day was reserved for Mt Rushmore and the Needles highway.
