I did most of the drawings for this book on Lake Michigan. Our home in Chicago was near the lake, and I’d go there with my daughters to play and swim, and sketch bathers. Since there are salty aspects to beaches, I flew back East and sketched seaweed and crabs. I remembered beaches I loved when I was young, from Fire Island to Cape Hatteras. Then I put all these sketches together into one summer day at the beach. So the beach in this book looks like the Hamptons but has Midwestern roots (the lighthouse here is at the head of the Chicago River). Even a city beach has details that make a beach a beach: sand, seagulls, and bathers in funny swimsuits.
