In June 1976, my eldest son (Jeremy) graduated from high school, and the two of us celebrated by taking a car trip, which brought us to Yellowstone. We were looking down at a wonderful view from a high point on the trail, when we noticed Ladybird at the same place. She was accompanied by just one male aide, probably a secret service person. This was just four years after the death of LBJ. We had a brief but very pleasant conversation, probably about the beauty of our surroundings, and I remember how friendly and gracious she was.
