When I visited, I took the park bus tour. The guide was a middle-aged Indian woman who casually mentioned that she was Crow. Whether she lived on the reservation or not, I don’t know.
Being my usual bull in the china shop self, I naturally asked if she got any static from Sioux and Cheyenne visitors about the Crow having been allied with the U.S. As you probably know, Custer’s scouts were Crow.
She smiled and said, “All the time, but we don’t shed blood over it anymore, except on the basketball court.”
The battlefield IS on Crow land, so if I wanted to be fussy about it, the 7th Cavalry was assisting the Crow in repelling a hostile raid.
The older Northern Cheyenne are no fans of the Crow. Their favorite saying is “as ugly as a Crow.” Needless to say, the Northern Cheyenne are a good looking people.
