Nope I never visited the German Democratic Republic, but my parents did it. Every time they pass the border, the boarder control take their passports for "inverstigations"...If the passed the control and they drove on the country road, police stopped them again to check their trunk again..just tormenting.
YOu have to know that a part of my parents come from western Berlin. So if they want to visit western germany, they HAVE TO drive through the GDR. So
western Berlin was a enclave. In this time you could flee to western Berlin, if you like to refuse to serve for the new founded, at that time, German
Armed Forces. They can't "take you" . So it was the "save" site for pacifists
