If the land you are crossing is desolated yet captivating, then there is an excellent chance you are in what AAA calls the Indian Country. Misappropriation of the name aside the Indian country is where one comes to see incredible geological formations and to witness the progress of a 200 years experiment in civilizing natives. You may think that the concept of bringing the benefits of Western civilization to autochthons is a thing of the past, offensive to modern sensibilities. But consider the restrictions on alcohol on Navajo reservation. The federal government forbids sale of alcohol on Indian lands unless the tribe allows and the Secretary of Interior certifies it. For the rest of us the default option permits alcohol unless local community curbs it. Which is more common than you think: a waitress in Blanding, UT apologetically remarked it's a dry town (and not because we were in the middle of the desert) when we tried to order beer with our dinner. The result, an utter lack of your favorite libation, is roughly the same but this is not a subtle distinction. Federal laws treat Indians like children. Just look at the extent of tribal jurisdiction over Indian country: the tribal court can only rule in case when both the victim and the perpetrator are Indians and only when the crime is a misdemeanor. Felonies and crimes affecting non-Indians are deemed to difficult to be left to native judges.
