After one train delay and rescheduling in Hamburg, I made it to Berlin Hauptbahnhof and thence to Alexanderplatz, where I immediately got lost because most of the space is given over to the Christmas Market. Or markets. There are two sections. Possibly they are rival markets. But they’re both much bigger than anything I saw in Copenhagen. And my phone battery died again, but I was able to use a map that I had that was printed on paper, like primitive humans used to use. Also, it took me longer because I had to eat bratwurst along the way.
