I was a traffic boy at Sutro School in 1945. I was amazed to find a picture of the 1945 School Traffic Review at Kezar Stadium. It and hundreds of other SF pictures can be seen at sfpl.org/librarylocations/sfhistory/sfphoto.htm Click on Digitized images by subject, and look for Stadiums, Kezar, No. 4. In the picture, uniformed ROTC cadets stand like dark trees among the shorter white-clad traffic boys. Sutro won in our division and I remember we taunted the Peabody School boys as we went back along Clement St.
