Miss Cupcake's son and daughter-in-law arrived late Mon night. Tue: took them to Mulligan's Beach House for breakfast, visited Blowing Rocks Preserve. The iconic rocks were sandlogged and the 2 blue crab nests we knew of were abandoned, but we saw some of the little black crabs on the sides of the boardwalk posts. And the largest orb-weaver I've ever seen, with a web right across the west entry to the butterfly garden. We noped out of crossing under, and backtracked to the other entrance. Mailed out E.-'s DDG while "the kids" enjoyed the pool. Buffalo chicken pull-apart bread for a late lunch, lasagna and a viewing of Elf to finish the day.
