I am planning to visit the Navajo nation (cycle touring) and I was thinking of learning some Navajo. Probably just very basic things, as I only have 5 months. My question is whether it is possible to practice the language there or if only very few people speak it. Also, as I am not Navajo, the feeling I've had so far (after trying to get informed about it through various other people) is a certain rejection, like "you're not Navajo so you shouldn't be learning it". Is this somehow true?
I like to learn the languages of countries I visit, but I am not sure if I am loosing my time with Navajo.
Please excuse my ignorance as I have never been there and I base my views on the reactions of very few people.
