Another shot at four square's history...
Dear Sean, I was reading the blog of a local upcycling carpentry company here in Cleveland, Ohio. "Piece of Cleveland" salvages lumber from razed buildings and creates new furniture. The former Stanard Elementary School was one. The Stanard site is now a big community garden. Some of those old bricks now grace my garden walkways. It has been rumored that our beloved game of four square was born on that playground. Could you confirm or correct that notion?
