I enjoyed the story about the Sprague. In June or July 1959 700 boy scouts from Pgh. hiked the Forbes Trail from Ft Ligonier to Pittsburgh and on a Sunday afternoon had a celebration in front of the Big Mama. I am trying to find written stories about this journey. I was one of those boy scouts age 14, and that hike was a major event in my early life. As I no longer live in Pgh. I wonder if there is a 50 yr celebration of that event. Thank You
