It rained very hard in the late morning and early afternoon. We set out in a northerly direction exploring, but turned back when the weather got too bad.
After lunch, I took the kids to the Portsmouth Children's Museum. Peter's favorite part we the yellow submarine climbing structure (on which he spent at least a half hour). Elizabeth's favorite part was the infant area in the top floor loft, though as the parent of a fast crawler, I could have done with some gates at the tops of the too-near stairs -- I didn't dare look at their selection of parenting books for fear of losing Elizabeth overboard.
We had dinner at Warren's Lobster House, which has a terrific salad bar and also has (of course) really good lobster. After dinner, we dropped of David and his mother at the house, and then I took Peter and Elizabeth for a beach walk.
At the beach, Peter busily inspected tidepools and found a shrimp (or possibly a young lobster) and a crab or two.
Elizabeth was outraged that I wouldn't put her down in the sand, but we weren't dressed for that. I handed her a beach rose someone else had picked and dropped. She ate it.
