On April 4, 1968, I was a 5th-grade student at JR Masterman Laboratory and Demonstration School in Philadelphia. It was a school within a school -- a school for "gifted" children within a neighborhood school for (I think) mostly Hispanic kids who lived in the surrounding community. I say, "I think" because we never interacted with the kids from the neighborhood school. I only saw them occasionally, from a distance, passing through at the end of a long hallway that we never crossed.
