@Ceili,
The long walk was the march of the Navajo to Bosque Redondo, which is Spanish for round forest. I was at the headquarters of Bosque Redondo some years ago, and can only say that the person who named it was long on imagination, or short of knowledge about trees. Trail of Tears applies to the Cherokee, who were mostly in the Carolinas, but ended up in Indian Territory in Oklahoma. Capitalize Indian Territory. It was a specific bit of geography, into which a number of tribes were forced. If one means land mostly inhabited by Indians, the term is Indian country.
Apaches and Navajos both use Athabaskan languages. I asked one of the Navajo girls I worked with, and she said it was the same language, but Apaches talked faster. She also said Navajos had more class, culture, and character. I never asked an Apache about that. Navajos in NW New Mexico typically call themselves Navajo when speaking English, and Dine (with an i) when speaking Navajo.
Navajo humor often relies on word play. I used to pass a small Navajo restaurant on the way to work. It was called the Diner bei Diner. The first word is Navajo, and the last is the English word diner. This is typical of what passes for funny on the Rez.
By the way, I've been to a pow wow and seen and heard many Indian drum circles, which is mostly a bunch of guys whaling away at this huge drum. The only drummings that struck me as worthwhile were by the Jicarilla Apache. Practically no change in rhythm, but a fascinating variation in intensity. They use a really big drum, and even the softest sections carry a long ways when the breeze is right.
Comanche are closely related to Shoshoni, and I don't believe either has any friendly relationship with either Navajo or Apache. I used to work at the Four Corners Power Plant and had at least a nodding and speaking relationship with hundreds of Navajo. I have never met a one that admitted to having ever known a Comanche. Comanches were mostly Texans, though they certainly raided into the Spanish settlements in New Mexico, and also raided Apache and Navajo while they were incarcerated at Basque Redondo. They were also the Bad Indians in The Searchers, with John Wayne and Natalie Wood. The movie was filmed in Monument Valley in Utah, though, and all the Indians were really Navajo.
Some writers familiar with both tribes consider the Navajo to be one tribe of Apache. There are lots of Apache tribes, by the way. I do wish JLNobody would drop in and clear up that particular point. I would take his soft spoken 'suggestions' as gospel.
Holy Mackerel. This must be one slow night for A2K to spend this much time rambling on about Indians.
