Born to the Wind (1982)
This was a show about a band of plains Indians (Cheyennes? Arapahoes?) on the eve of contact with the whites. I admit that I only saw 1 1/2 episodes when I was 17 (1982), but I remember that it was real quality TV. The episode I remember is when a couple of the men find a French trapper, something none of them had ever seen before, and the tribe was trying to decide what to do with him. Very different from the usual dreck on TV. Kudos for *someone* for giving it a try. I just wish it lasted longer, but that's what happens to really good TV.
Will Sampson headed Born to the Wind's cast as Painted Bear. Other actors in it included A Martinez, Henry Darrow, and Ned Romero. I don't know many of the cast members, but they seem to be primarily Indians and Latinos.
