The article about the Berlin Wall brought back memories. As I grew up in Berlin I remember “ Kristall Nacht” as I was about 15 at the time. Although I left Berlin before the wall was built my parents lived in the Eastern part of Berlin and could not go to the West. I managed to visit them as I was a U.S. citizen by then and remember how extremely difficult it was to get into East Berlin via Checkpoint Charlie. I am so glad it is all history now.
