If you are heading to Mount Rushmore will you also stop by the crazy horse monument? It is close by and looks like it would be worth your time. I was at Mount Rushmore in March of last year and did not go to see crazy horse. I wish I would have. The weather that day was not the best cold, windy, rainy. That does not mean every day would be like that in March though! There is a walking tour I would like to go back and take, it was not offered at the time I was there. The viewing platform is quite a ways away. Oh, you can see it all just fine! I just liked the looks of the walking tour. I was travelling for work, so was in a car and I do not know what any of the campgrounds etc. were like. Sorry! Take your camera, it is an awesome sight!!
