Hello my friend @gabmr,
I never did go back, although I wanted to very much. For most people, Spain is off the beaten path. When I went in '72 it was with my mother, who was not well at the time and wanted to see specific sights (she was losing her eyesight) as long as she could. These did not include Spain. When I went in 2000, it was for a niece's wedding in Lorraine, France. I went with my sister, who had never been to Europe, and once again I let her decide the itinerary mostly. We had a great time, but her wish list did not include Spain.
I'm not greedy. I had that summer. I have those memories. As you say, bright memories. I am content with that.
Thanks for reading and commenting. Be well 🌈
