In the Bay Area, the homeless are suffering more than usual from a cold snap that has killed at least seven people. In New York, the homeless are suffering about as much as they always have, and they are everywhere. Seeking to tell their stories, artist Andres Serrano embarked on "Sign of the Times," a project to buy 200 signs from homeless people at 20 bucks a shot to offer video testimony of their hard lives. When he asked, they always said yes, sometimes with a hug.
"I see every sign as a story. There are many stories out here that deserve to be heard."
