We went to sleep (on a boat) in Denmark.. and woke up in Norway! Country #5! Sure, we were only in Germany for half a day, and Denmark for 24 hours, but .. still counts!
One sad thing about the way our trip was structured is that we didn't have a lot of time in a lot of places that we would have liked to have a lot more time.
Where were we? Ah, yes, the Hamburg Train Station at midnight on a Friday. (To be fair, at the time I had no idea it was a Friday. We pretty much never knew what day of the week it was.)
