Book excerpt: It's the day of the county fair! Three-legged races, a "Smartest Pig" contest, the Ferris wheel—what could be more fun? But the Greenstalks' car won't start, so they'll need some help getting there. . . . Cows to the Rescue is the fabulous new book in John Himmelman's hilarious barnyard saga. It follows Chickens to the Rescue and Pigs to the Rescue, bringing back the fun with brand new mishaps and brand moo—er, new—problem-solvers.
