I've been doing the 'Sherman's Lagoon' strip for about 18 years, and I was a political cartoonist before that for my hometown paper in Alexandria, Va.
My imagination was no competition for nature.
So from that day on, I was an ordinary kid walking around on dry land, but my head was down there, underwater.
Sometimes making a story is as easy as putting two characters in a room and seeing what happens. So, imagine a great white shark and a giant squid in the same bathroom.
I'm a big diver. I like to dive when I travel, and my last dive was in the Galapagos. I used to live in San Francisco and I would dive all the time in Monterey.
I've always admired sharks because they have a dimension of intelligence that is somewhat unique to that animal, and especially a great white. A great white has this organ called an ampullae of Lorenzini, and it can actually sense electromagnetic disturbances.
