Does anyone still scuba dive off La Jolla, getting abalone?

As a kid I use to scuba dive right off La Jolla Cove, bringing back several abalone and after processing them at the house, would chow down while watching the beautiful sunsets.

I have heard from friends still living out there, that the waters are not as clear as I might remember them being since alot of chemical pollutions have been dumped into the coastal areas of the Pacific Ocean from factories and sometimes, if standing high up on a cliff and looking down into the ocean below, you can clearly see the discoloration in the water.

Do people still rent sail planes at Torrey Pines, or has this been outlawed as well?
Roderick F, thanks for the great answer, and I too miss all the big abalone that use to be so available for the taking.
I tried to get some abalone recently from a friend of mine in SD, but he told me that they are dying off due to the chemical pollutants being tossed into the waters, now, the only way you can get abalone is from the farms, inland that raise the abalone and sell them, but I am told that the great taste is no longer there with the farm raised versions. I wonder if there are some big abalone off the Baja coast, off of Mexico, might take a trip down there next month and check it out. Used to go surfing down there a lot when I was a kid, great waves, especially when storms are brewing out at sea. Business will take me to Sunnyvale, CA to speak to the people who operate Yahoo! Inc regarding a complaint I filed against one of their employees for computer hacking, so in between meetings, will have some time to take the trip south.
I lived in La Jolla, PO backyard, thanx!
