When I was a boy, my grandfather told me stories about taking his niece out for car rides because "that is the only way she'd fall asleep."
When I was a dad, my daughter would frequently fall asleep when we were driving around in the car.
When I was a writer, Phyllis Root suggested trying to write a picture book text in under 100 words. At that time, I was also working with the composer Libby Larsen on a concert involving students and sound, and I was paying a lot of attention to sound.
All of those things went into Vroomaloom Zoom. The book, with great illustrations by Joe Cepeda, had a fun run in both hardcover and paperback, and then went out of print. Now, however, I've found another publisher who is willing to bring Vroomaloom Zoom back for another lap.
