I didn’t see much of anything in South Dakota until I got past Wall Drug. And it wasn’t the ice water that opened my eyes. It was the Badlands. Okay, so you can’t grow crops there, but that makes it even better to look at. Mount Rushmore is impressive, too. In 2010, I finally got to see the still-in-progress Crazy Horse monument a few miles away, just north of Custer. Will it ever be completed? Check this page in about a hundred years ...
