If You Know A Beachcomber In Northern California

Hi everyone. I need your assistance if possible. I am visiting family in California and we drove out to Baker Beach in the Presidio Park in San Francisco. We were surprised by an extra large wave and I lost a small camera (Nikon P300) and two little bags of camera cards.

I am hoping that the camera cards will someday come in on one of the low tides before they get too damaged, and a treasure hunter or metal detector might find them washed onto the beach. I figure the more I spread the word, the better chance I have although I realize it is a very big ocean. The camera cards are in zippered net bags (one red, one yellow).

Thank you for your help.
