Hot cars

No parent wants to live with the guilt and grief of leaving a child to die in a hot car. For Raelyn Balfour of Ruckersville, Va., "It's something that's always there."

Balfour's 9-month-old son Bryce died of heatstroke March 30, 2007, when she left him in her car at work at the University of Virginia in Charlottesville. Bryce was one of an average of 38 children who perish trapped in vehicles every year, according to KidsandCars.org, a nonprofit organization that tracks death rates and advocates for child safety in cars.
