Russell Pate was driving through a neighborhood one late afternoon when he noticed something odd.
He couldn't hear the sounds of children playing. No jump rope patter. No squeals of a bike's brake. No crack of a bat -- just silence.
The streets were deserted because the neighborhood kids were cocooned in their homes, Pate says. It was a scene he's seen over and over again.
"Now you can drive through entire neighborhoods where you know there are a lot of young kids there and hardly see any of them out," says Pate, an American Heart Association spokesman.
