We are from southern California, where you are towel-to-towel with about ten zillion other people in the summer. Here the beaches feel deserted, even when busy. On the Bay side, where the Citadel is located, the mood is serene. We dropped a shoe one day. About eight days later we found it on someone's private wall between the Citadel and the beach. They saved it for us and set it where we would find it. Unheard of in California.
