We traveled from Buffalo, Wyoming to Hill City, South Dakota today. We stopped at Devil's Tower National Monument. It was the first national monument. We hiked around it's base and the kids completed the requirements for the Junior Ranger program. Close Encounters was filmed at this site. There is a field of prairie dogs near the entrance that were adorable. Tomorrow will be busy as we visit Mt. Rushmore, Crazy Horse and hopefully at least one other national park or monument.
