On the seas–first C was for castles. Rented a car in Copenhagen and went where Carolyn wanted–to the castle at Elsinore, setting for Hamlet, a wonderfully dismal setting for a 
wonderfully dismal play; two other castles. Then we joined the cruise, where we lowered the average age by 20 years (key question–what did you do before you retired?); Copenhagen is full of castles and we saw lots of them.
The next C was cod, for where we w
ent to an island that had a round church (which was also a castle–protection for the local folks) but the island is the biggest supplier of cod for the McD chain!
Today we were in Gdansk, which was 70 percent destroyed during World War 2, but has been restored (under the communists). Delightful city, with castles and churches. 
Highlight was seeing Lech Walesa museum and him in person. He said he hopes he is the last revolutionary (led Solidarity, which unraveled the Iron Curtain), because then no one would have to tear down his statues. Neat day.
May have better access tomorrow. We’ll be on land at a hotel in Vilnius. Been doing yoga on deck–it’s great.
