We only had one interesting stop today: Mount Rushmore National Memorial. It was pretty impressive.

After that we headed east across South Dakota. Probably the most boring state so far in terms of scenery. Flat with lots of farms. Luckily the speed limit is still 80mph. I wanted to detour through the Badlands, but Yanmei vetoed it, which was probably good in retrospect because we didn't get to our hotel until after 9pm. We crossed into Central time zone, so we lost an hour today. We're staying the night in Worthington, Minnesota.
