This episode focuses on native language teachers working in schools on the Wind River Indian Reservation in Wyoming. By teaching the Eastern Shoshone and Arapahoe Native American languages, they hope to both preserve the native culture and undo years of erasure, where Native American children were routinely punished for speaking anything other than American English. Host Geoff O'Gara speaks to some of these teachers to about their efforts. "Main Street, Wyoming is a documentary series exploring aspects of Wyoming's local history and culture."
