One of my favorite things about the show - they did not portray the Cheyenne as stock characters but as a whole range of personalities just like every other ethnic group on the planet.
I know Cheyenne. Way more Salish, but Cheyenne too... Yeah, folks is folks. But the interplay between the various characters is what it really is like - Natives vs white... There is a suspicion there, Just like what is portrayed.Not racist, necessarily, but different, and uncomfortable with the difference.
And a real bleed-over between the two cultures where they find mutual acceptance - Hillbillies around here have a whole lot of native culture woven in. I wear mocs, have a throat patch... feather laying down in my hat... Turquoise and silver... I carry a name with the Salish and the Cheyenne. I have sat in on many a sweat.
That inter-operation is real
