Please check out the Family Reunion Meetup site. Patti was suggesting some things to do and I added a bunch of other free but fun things to do in the area. There is also a photo album with some of the sites.
There will be a rare -1.8 low tide. The Tide Pools in Moss Beach are fantastic when the water gets that low. People come from a hundred miles away when such low tides are forecast. You can walk a long way out in the ocean on the rocky ledges of the tide pools and see lots of anemone and sea cucumber as well as starfish, clams etc. And even an occasional octopus or squid.
Several people have RSVP'd but many others have not. Please comment either way and enjoy the sights in advance.
