To celebrate the 30th anniversary, we all went on a trip to Berlin. There, in addition to lavishly testing the local catering establishments, various activities were undertaken, such as a Trabant Tour and visiting monuments such as the former border post and now museum Checkpoint Charlie and the remnants of the Berlin Wall, the Brandenburg Gate and the impressive Holocaust monument by architect Peter Eisenmann. But most of all, there was a lot of fun in the German capital.
