I'm part Indian-and I usually just use the word Indian when I tell someone, although I realize it is not accurate. Native American is better, I just rarely think to use it and no one has ever been offended. It doesn't come up very much, in any event.
I am one-fourth Cherokee, and when I was in college I had a friend who was Creek. He used to call me an apple, because I was red on the outside and white on the inside, and it's true, that my siblings and I were not raised as a part of the Cherokee culture at all. Most people who are Cherokee in Oklahoma live in Tahlequah.
I know that's off topic, and I apologize. The various stories of where people were and the peek at their lives is quite fascinating, along with the undercurrent of sorrow.
