here is some berlin stuff that could be related to your experiences. cus the video is from -Berlin Tempelhof- the airport. I doubt u have been in eastern Berlin in the 70s. But this is quite new. Tempelhof is now a "Parkside".
The pics maybe refreshing your positive memories a bit
@plastisch Forgive old man but my vision of Berlin is stuck around late 70's when interesting stuff was happening. Never considered myself a tourist , strongly dislike the very idea but i happen to visit interesting places from time to time. There is a difference ,belive You me Just hopeing there is something left of that Berlin worth visiting , cheers.
