Location: Köthen – Triftsee – Mittelsee – Schwanensee – Wehlaberg – Mittelssee – Pichersee – Köthener See / Weather: 27°C, sunny / Distance: 11 km  / We spotted some grass snakes (natrix natrix) lying in the sun next to Mittelsee and have been really flashed by the size of the Tropical Island building seen from the look-out of Wehlaberg.

There is extraterrestrial life (very big and very small)! The first thing is the Tropical Island building, an architectural monstrosity  – with an independent climate – formerly used as a construction plant for airships. And I have no clue what those small shiny things are. Do you?
