The Plains Indians by Ginger Simpson
Amazingly enough, though many tribes lived and co-existed on the Plains, the language spoken consisted of only nine different ones: Siouan, Kowan, Caddoan, Algonquian, Shoshoean, and Athabascan. It’s not surprising that sign language became a means of communication for those who didn’t speak the same dialect.
For centuries and centuries, Indians have depended upon the buffalo as their mainstay. In fact, before horses were introduced as a means of transportation, nomadic bands hunted on foot. Of course, you can safely assume that the lifespan of these hunters was relatively short because of the danger involved. Have you seen the size of a buffalo?
Have a Nice Day, or as a Lakota woman would say: Aŋpétu wašté yuhá pe.
