A very enjoyable day extremely well organised by Margot Dietzsch, Thomas Lenk, and Joachim Wenzel. Joachim led a longer walk, and Margot led and narrated an interesting walk around Tegeler Schloß, themed around the brothers Humboldt.

Everybody then boarded the Moby Dick at Greenwich Promenade for a lovely two-hour boat tour, and we finished off the day with a meal at Tegeler Seeterrassen where they coped smoothly with an onslaught of 38 people who all ordered different courses.
