I had already left the Detroit area and was living and working in upstate NY when I learned of the riots. My parents were still alive and living in the downriver area. I decided to come home to visit and try to calm them. I recall vividly exiting the tunnel and after the customs check the officer saying, "don't you know there's a riot going on?" Of course I did. I recall getting on the Edsel Ford doing ~ 90 mph. There wasn't a car in sight. There were no problems downriver and by the time I left to return to NY it was all over. I never had a good realization of the causes. It would be a few years later when I hear Gordon Lightfoot's recording 'Black Day in July.' I had a better idea of what happened and why.
