And what a trip. With her gander Charley and her goslings, Petunia sighs as she wonders where the airplanes go that fly over the farm. Alas, Petunia cannot fly. She's too fat. But ""CALISTHENICS"" remedies things and Petunia, now fit, not fat, flies right to the city, makes friends with the policeman, sees the sights, but soon begins to feel so small that she's happy to return to the country. Humor never absent from Duvoisin's steady talent as a writer and artist.
