Publisher's Synopsis
Sam loves to watch construction work. Every day, he stands behind the fence and watches the big machines--the steamroller, the cement truck, and the tall crane--in action. When Sam enters the construction site on a dare, he discovers he can operate the big machinery! With a surprise ending, Sam saves the day with his construction site know-how. Hidden clues and delicious details make Alice Hoogstad's construction site a feast for the eye.
