We went to the Black Hills last year. On the trip out, we happened to be camping next to a couple from the Rapid City area. This is what they told us; take from it what you will.
They said that tribe that is building the monument has had public and private financial offers to finish it, but they have refused the help. Some in the tribe are living like royalty on the fees & donations, and a lot of that money will dry up when the statue is finished. That is also why there is so little progress in the carving of it. They donít want to stop the gravy train.
We chose to take a picture of it from the highway, and spent the money at the Mt. Rushmore gift shops.
We also stayed at Beaver Lake campground, and it was great. The bunnies running around the campsites were tasty..........just kidding, they were cute. Just be aware if you have a dog.
