There was an incredible article in the Post today about the Tsaatan tribe in Mongolia who are reindeer herders. Mongolia claims the lowest inhabitant-to square mile ratio of any country. Something like 4 people to every 40 square miles. Their particular language [some form of mongolian?] is becoming extinct. The most local, and the last, teacher of the language went to the capital to get better pay so she could support her daughter, an aspiring contortionist.
