Nellie Sue is back and she’s taking her cowgirl flair to the county fair. There are games to play, animals to pet, and rides to go on. But of course, Nellie Sue is really looking forward to the Bike Rodeo. She hopes that practicing will make her and her two-wheeled horse good enough to win against the reigning champion and her friend, A. J. Pickett. When a nearby goat gets loose and threatens to ruin A.J.’s ride, Nellie Sue knows that it’s her job as an honest cowgirl to step in–even if it means coming in second place.
