Every morning school buses large and small leave the parking lot where they are lined up by the dozens and make their respective journeys across town to pick up students and take them to school. The buses hit the roads with their seats and windows empty. They cross intersections, stop at traffic lights, and the students they pick up fill their windows with color and movement. After dropping the students at school — and doing so "right on time" — the buses wait for morning to pass to afternoon. Then they return to the schools, take the students home, and return once more to their familiar lines in the parking lot. It's a simple story told with predominantly one sure and trustworthy color — school-bus yellow. With few words and detailed illustrations, Donald Crews shows the travel to and from school from the buses' perspective, and a journey that might seem harrowing to early school students is made familiar and almost welcoming. If there is one thing you can count on in these pictures, it's a trusty school bus.
