When 67-year-old David Lavau drove away from home, he had his cell phone turned on, a decision that saved his life. After missing for six days, his children, relentless in their effort to find their missing father, followed information that a sheriff's detective provided: the records of the cell phone's location. That detail gave Lavau's children a general area to look, but it was a large and remote mountain area with canyons and ravines that could barely be seen from the road.
They persevered and found their dad within hours.
So, take that cell phone whenever you leave home; that doesn't mean "dialing" while driving is a good idea, but simply having it in the car, turned on, transforms the little modern convenience into a potential lifeline.
