Hundreds of people sleep on San Diego's streets each night, on corners, beneath the interstate and across from the public library. They hang out in small groups or sit alone, watching the time pass. But when a wiry man with dark glasses approaches, everyone seems to perk up. The man is David Ross, better known as Waterman Dave. For years, he's handed out hundreds of bottles of water each day to the homeless. He's a 75-year-old retiree who's made it his mission to help the homeless-- even if it's just with a hug or a kind word.
