I studied in the german school here at Valencia, and thus learnt specifically german geography as well as went many times to germany. Cities of germany I think of spontaneusly are those where I have been in those trips.

Freiburg, München, Hamburg, Kiel, Lübeck, Stuttgart, Frankfurt....in fact I am more or less much familiar with all the south-west of germany. And would you believe it? Me idiot was some years ago near Laboe and I had no idea of U-995 being there

so I missed the visit
