Crater Lake

Dear Diary,
still heading north towards Portland & Seattle as planned. Filled stomach: ‘Hunter’-Burger at Beckie’s tasted A+. Next stop certainly has the most imaginative name for a lake, in a crater. Crater Lake.

Old Tanneries

Cottbus, DE
Dear Diary,
Chóśebuz is a very old city rich in tradition. Due to smelly business, the tanneries were required to be built outside of the former city wall. One of the most famous persons here is Fürst von Pückler - worth a read. Visiting our friends at JodelHQ in Berlin and spending the weekend with Oliver for local sightseeing.

Kleinwalsertal, AT
Dear Diary,
our yearly retreat once again takes place in the beloved Söllerhaus. Besides some snowboarding, we had lots of valuable discussions about internal processes, teaching, project(-acquisition)s and future science. Did you know that this place had been owned by RWTH?

Peleș Castle

Cambridge, GB
Dear Diary,
the historical city of Cambridge definitely is worth a visit! You literally can feel a weird Bri’ish academic culture on the streets. If you were wondering - accomodation at Churchill College near the UCAM Computer Science facilities; and a lovely dinner at Sidney Sussex College.
