When in Hamburg Do As the Hamburgerinnen do

In Sundays in Germany, people do little more than brunch for the whole day. Knowing this, I chose to leave my planned bike riding for today. The only decision I felt I had to make was where to have lunch. I chose to stop for asparagus soup and pans cotta with strawberries on the outdoor terrace of the International Maritime Museum.
I got a nice view of a plaza decorated with polished tanker propellers and the Pusan Brucke, a refurbished bridge over something called the Magdeburger Hafen, a muddy basin which hosts the occasional small harbor cruise tourboat every couple of hours.
These are people on the 2 hour Speicherstadt boat tour from Landungsbrucke.
In the two days I've been here I've not seen anyone on an SUP or in a sea kayak toodling around the harbor, the way I do in Elliot Bay and the Port of Seattle. Perhaps the rules are tougher here, given the proximity of the super class container ships.
Instead I've contented myself with people watching. First a woman my age reading a book called Wolfspirit by Gudrun Pfluger, who, at least by the book's cover is either, a zoologist like Dianne Fossey, except not gorillas but wolves. Or else, she's a German Shirley MacLaine helping women get I touch with their internal "wolfiness."
Later I watched a guy in a pristine Mustang convertible do a tight turn on the cobblestones terrace, narrowly missing the decorative propeller blade sculpture.
A good use of a Sunday in Hamburg.
