From a Guardian Children’s Books site interview – full piece recommended
Where’s your favourite place to write?
I always like to work outside and our house has two outdoor decks: a lower one, which I don’t use, but the upper one is open to the sky and I’ve got my hammock out there and my rocking chair. It looks out over San Francisco Bay and its up on a hill so I can see San Francisco and I can see Alcatraz and I see the ships going by and the sail boats and all that kind of stuff. So that’s my number one place to work. But when its too cold, I drive my car over to what’s called the Marin Headlands and I’ll stop in the pull out where all the tourists come to take pictures and I’ll type in my car. I also work in coffee shops sometimes and I work in bars sometimes and restaurants.
