The senior experts go on excursions together. At these events - preferably a mixture of culture and chemistry - the focus is not only on discovering new horizons but also on social contact between the seniors. In addition to the seniors from the GDCh, the seniors from the VAA, the Hanau-Wolfgang plant group, usually also take part in these excursions.
This first excursion on 23 May 2007 was organised by Holger Bengs; all further tours were organised by Wolfgang Gerhartz, partly with strong support from Eva Wille, Klaus-Peter Jäckel and Hans-Uwe von Grabowski.
