Wow! Not sure where to start, so will start at the beginning. The staff at the entrance is welcoming and knowledgeable. Billy ( a Sioux) presents the most interesting and accurate picture of the past and present day Sioux culture. The Operations Manager and her assistants add to the experience at this must see attraction. The sculptures and other outdoor exhibits are, along with Crazy Horse Memorial Museum, the best we saw on a trip dedicated to learning more about Native American culture and spiritual practices past and present. We are most grateful for the courtesy and humorous banter of the staff.
