yes, La jolla one of my favorites also.
The marine sanctuary there is teeming with wildlife which gets very used to having people dive and snorkel there.
Just 10 feet off the beach and you see seal/garibaldi/sand shark and all sorts of fish.
It's a shame as people still like to take advantage and just recently a spearfisherman shot a 200 lb bass in the protected cove.
He is now facing jail and a stiff fine
Seems the fish was so tame ,it used to be a local charachter and approached swimmers often. Lots of skill in spearing that
