Ooh, it's cool to know so many languages, even at a tourist level! Navajo sounds wicked, but have you ran into any trouble finding material/classes where you live? With Welsh the classes are often subsidised by the government, who only have jurisdiction in uh, Wales, naturally. Being in East England makes it difficult to access resources (for example, a county-wide directory search revealed that there are ZERO Welsh-language books in any library within 100 miles of me), so have you found Navajo better catered for? If I'm honest, I don't know much about its status in America like, is there an active governmental effort to increase the number of speakers? Please enlighten me!
