Thanks. I will follow your advice -- pretty much what I thought.
It was fun to see the sea lion, and I'm glad there wasn't a closer interaction. I wasn't nervous (well, until I managed to kick myself and wondered what that was...
I've been up close and personal with harbor seals, Naji, when kayaking at Moss Landing. Like you wrote, they'll come right up and bump. They were very persistent.
As for sharks, I hope I never need to follow this advice! I've been around reef and little sand sharks, so they don't freak me out. But the big guys west of SF Bay are not the ones I want to be near.
