Not too far back. Notice the shopping cart? Looks like a photo from the seventies to me.
I can remember when our upper east Tennessee high school was desegregated - 1966. Not sure of why it took that long. I think there was a plan to begin integration in the elementary schools and do it by increments.
Whatever. I recall seeing the new black kids, all neatly dressed (some carried brief cases, which we white guys thought odd.) But, what I noticed was the fear I saw in some of their eyes.
So, I introduced myself to Clarence. Now, we did not become best friends, but we had at least a level of human interaction and just maybe, he was a little less afraid.
Clarence was killed in Viet Nam a few years later, as was a white acquaintance - Joe Mead.
July, 1973. Just a wild guess. ;-)
