Saturday in the park. long ago

I always wonder where the time goes and hoe ephemeral life is. Thanks to a good memory, I recall a time before the web and smart phone when people interacted with those close to them. Central Park in the seventies was a place of great crowds and of free spirits intent on making the scene. It was a wonderful time; one hard to describe with words. A photo may help. This is a Kodachrome scan.
