The Teton School District 401 Board of Trustees voted on May 10 to make masks optional at all schools for the remainder of the academic year, effective May 11. Superintendent Monte Woolstenhulme introduced the idea because Teton County has seen a steady decline in its active Covid case rate over the past months, and because all adults and teens 16 and older can now easily get the vaccine. On May 10, U.S. regulators approved the Pfizer shot for children as young as 12.  "The numbers show we should be backing off of what we are requiring people to do," Woolstenhulme said. "The data proves that."Â
