The pigs, Pete and Paul, are eager to help Farmer Bill grow the best and biggest watermelons so he'll win at the annual Fruit and Vegetable Show, but their overzealous efforts to help the melons grow faster end up destroying the entire melon patch. Tractor Mac and friends teach Pete and Paul that with patience and care, they too can grow a prize melon. Billy Steers is an author, illustrator, and commercial pilot. In addition to the Tractor Mac series, he has worked on forty other children's books. Mr. Steers raised horses and sheep on the farm where he grew up in Connecticut. Married with three sons, he still lives in Connecticut.
