Took the tube (always) to Greenwich. GPS on new sim card stopped working (of course) and Bob took Marilyn on one more ”death march”. Wouldn’t be a vacation without one.

Stood on the Prime Meridian — one foot in the Eastern Hemisphere and the other in the Western. Then we stood in different hemispheres and held hands.

Talked to, and took pictures of, a very nice couple and their kids from the Netherlands. They gave us some suggestions of where to go and what to see when we arrive.
