I discovered a YouTube video of my old elementary school, Ravinia School, with footage from the ’50s. I started kindergarten in 1957. The video shows the Robin Hood mural by the office and kids playing on a piece of playground equipment that was taken down just before I was old enough to try it because some kid broke a collarbone. (I’m still bitter.) Ravinia now has 300 students; at the height of the baby boom, when I was there, we had more than 500.
