Oh, okay, I figured someone would have chimed in by now? I have second-hand information, but I believe there is some reliability in it. The South-bay does seem to have some sharks and rays. I have seen pictures of keeper sized leopard sharks and some bat rays at Alameda Rockwall area, Dumbarton Pier, and shore spots that look like Brisbane (Candlestick Park area) and Oyster Point Pier. Seems to be more action than parts of the East and North SF Bay to date.
