Rex and Rose Mary Walls had four children. In the beginning, they lived like nomads, moving among Southwest desert towns, camping in the mountains. Rex was a charismatic, brilliant man who, when sober, captured his children's imagination, teaching them physics, geology, and above all, how to embrace life fearlessly. Rose Mary, who painted and wrote and couldn't stand the responsibility of providing for her family, called herself an "excitement addict." Cooking a meal that would be consumed in fifteen minutes had no appeal when she could make a painting that might last forever. Later, when the money ran out, or the romance of the wandering life faded, the Walls retreated to the dismal West Virginia mining town -- and the family -- Rex Walls had done everything he could to escape.
