Patricia Riba has a high-paced job as chief of pediatrics at a Huntington Beach community clinic, a full plate of volunteer work and an active young daughter, but what keeps her awake late at night are images of Orange County's homeless.
Riba thinks about the 21-year-old mother, eight months pregnant with her second child, who rode public buses non-stop at night because she had no place to sleep. She thinks about the homeless couple in their 70s living in their car, and the mother whose legs are both amputated, living in a motel with her children.
