A winding highway; children fighting in the back seat; parents suggesting diversionary games and holding onto their own hopes and fears for the vacation ahead. It's not an uncommon scene. But it is Donald Davis's genius that turns a lackluster family vacation into a week to remember. The 1950s-era plastic seat covers were not the only thing to leave a lasting impression. In her spontaneous (and desparate) invention of games like Cow Poker and See Rock City, Mother keeps the rules one step ahead of the back-seat contestants, until one-too-many choruses prompt a detour the family never forgets.
