Mt Rushmore to Bell Fourche, SD
You know this picture. It has been taken millions of times through millions of cameras. It might have been hyped enough as to be seen as patriotic kitsch by some. But, come one... you're in the Western side of South Dakota. You like the idea of driving around the fascinating, unique & complex geological structure that is the Black Hills of South Dakota. There is no harm in it. The mountain air is magnificent and refreshing.
When you get to Mount Rushmore notice the license plates... they are from everywhere. Notice the people. You will hear regional dialects from all over the US and languages from all over the world. Get out of your car, walk around, watch the tourists... it's fun. There is one point to note: the hillside faces East so you will get the best light if you get there early in the day.
