Captain Cook's Cove is a beautiful area with a monument honoring the explorer credited with "discovering" the Hawaiian Islands surrounded by some nice coral reefs.  Shannon rode a wake board with a long-sided swim mask built into it ... which allowed her to see the reefs and tropical fish, sharing the snorkeling experience with Nora and I.  She was fearless in her float belt and water wings, swimming out hundreds of yards away from the boat with me.  Nana hung out on deck and was the official trip photographer.
