I knew I had entered a different state when the speed limit increased from 70-80 mph. Welcome to South Dakota. The temperature today hovered around 90, unusually warm for this time of year, but not as warm as yesterday’s 97+. Passing over the Missouri R. there’s a dramatic change — in elevation and in the landscape (rolling green, grassy hills). And then there are the Badlands; in a word, spectacular, but pictures tell the story far better than words ever could.
