This morning (20 Aug 2020), Sanford “Sandy” Baumgardner, an Andover High School classmate, sent me a photo from the 1950 Boy Scout Jamboree encampment at Valley Forge. The photo shows the scouts attending from northeastern Ohio. I am shown seated fifth from right. Next to me, fourth from right, is Sandy’s older brother Hugh (now deceased).
We made the teepees from a waterproof composite material that I believe farmers used to line silos to store silage.
According to Wikipedia, the 1950 Jamboree was held from June 27 through July 6, and was attended by 47,163 scouts and leaders.
