The next morning it is not far to South Dakota. We slowly go through Wind Cave National Park and stop frequently to watch the wildlife. There are several hundred bisons living in the park. We are lucky and get to see some of them.
Just north of it is the Custer State Park ($15). The narrow road is winding up and down the hills, even with tunnels, through a beautiful scenery. At the end there are the first glimpses of Mt. Rushmore.
At Mt. Rushmore there are masses of tourists. Parking there is $11, and of course there is no room for stopping long before. But the sight of the presidents heads carved out of the mountain is indeed impressing.
