Laguna Beach, CA -- Dive buddy Bill and I prepare for a dive to Mermaid's Grotto. Twice I think I've seen those pesky sirens taunting me at 60-ft below the surface in the magical forest of kelp. People usually ask what I see when I come up after an hour's tour under the sea. I tell them exactly what they want to hear: "I see mermaids, man-eating sharks and Sponge Bob on occasion." We all get a chuckle.
