Father, son, and Bitsy the dog take a 100-mile car trip to Grandma's house. They go through the city, race with train cars, survive a rainstorm, stop for snacks and eventually wind up at their destination. Every 10 miles, though, the son asks, "Are we there yet, Daddy?" and is told to consult the map. The map and the route are shown so children can follow along. The son's growing boredom, the father's increasing annoyance, and the changing countryside are all cleverly and subtly shown in the watercolor illustrations, and the story is told in a simple, repetitive rhyme, which captures the rhythm of a road trip. The book teaches basic math and map skills in an enjoyable way that will encourage both beginning readers and listeners. Marta Segal
