The #1 New York Times bestseller! Big trucks may brag and roar, but small and steadfast wins the day in this cheerful story with timeless appeal. On the Mighty Mountain Road Crew, the trucks come in one size: BIG. That is, until the little snowplow joins the crew. None of the other trucks think that the little snowplow can handle the big storms, but he knows that he can do it--and just to be sure, he trains hard, pushing loads of gravel, pulling blocks of concrete, and doing plow lifts to get ready. But when a blizzard arrives, will the little snowplow's training be enough to clear the streets and handle unexpected trouble? Taking its place beside classics such as The Little Engine That Could and Mike Mulligan and His Steam Shovel, this tale of a plucky little plow will find a clear path to readers' hearts.
