Chuck used to do it a couple times a year when Kawika was alive.
I'd go in a heartbeat, but I don't think my little inflatable would be the safest ride.
When I said the rocks near Ocean beach, I mean the ones right near the Cliff House (or whatever it's called now).
The Farallons would probably be a great dive. The only downsides probably being the distance and you floating around looking like a very slow and uncoordinated seal.
I think those rocks are collectively called "Seal Rock". Those would probably make for quite a burly dive. Probably a little more than I'm looking for in a leisurely afternoon dive.
