Old MacDonald Had a Truck Children's Board Book by Steve Goetz. Old MacDonald had a farm E-I-E-I-O. And on that farm he had a...TRUCK?! With a DIG DIG here and a SCOOP SCOOP there, this classic folk song just got revved up! Beloved machines the excavator, dump truck, bulldozer, and more will have the vehicle-obsessed of all ages reading and singing along.
