I left the rest of the family to have a day at home to recover from the excitement of (and resulting mess from) the beach trip to go to our soon-to-be useable church facility. We painted all the walls in one large meeting space, finished off constructing some other walls, did some priming and removed a huge amount of debris. Quite satisfying, but a fairly relentless day of work.
I understand that the girls spent a good deal of the day swinging. Here is a library picture from Day 2.152 of the girls in the pyjamas testing the strength of the ground anchors. They held up fine.
