The creators of the Construction Crew series take to the road for an irresistible guessing game about things that go.Rumbly wheels, grumbly wheels, Hauling-up-the-hill wheels.Wheels go fast, wheels go slow.Shout what's coming, if you know! A motorcycle has just zoomed by, and now a woman in front of the hotel is waving at something. What could it be? Men are clankity-clanking up the street pulling bins — what must be rumbling up behind? And what could those schoolkids be watching for at the end of the day? If the vehicle is on wheels, it's likely to show up in this lively picture book inviting children to join in at every page turn.
