Switch, you could do it like the Simpsons. There is a Springfield in most states, but they never identify which state their Springfield is in! That way, for one episode, it may be a port city. Two episodes later, it's a desert setting; three episodes after that, it's in the mountains. I'd love to live in a city like that with different environments for different days of the week!
I live there, Southern California. Mountains, beach, desert, all within easy driving distance.
By the way, I didn't bother researching them myself, as there isn't any handy-dandy Native-American language search engines. Sigh! (These web-designers really need to consider the needs of us Independent authors more often when creating multi-million dollar web-sites.) 'D
CW, You need to be more specific. There are dozens of Native American languages, in three or four language families. (We Europeans are spoiled, or maybe deprived, in that most of Eurasia has one language family (Indo-European))
