Five years ago, Frank Warren started a little art project called PostSecret. He handed out 3,000 postcards to strangers and asked them to anonymously write down their secrets and mail the cards back to him.
It was an overwhelming success and he created a popular website to show off the cards. Warren still gets about 200 postcards a day. Now — he's taking the secrets on tour. Postcards are currently on display at the Bedford Gallery near San Francisco.
Martina Castro is a producer and reporter with KALW in San Francisco. She decided to conduct her own social experiment. She went to the PostSecret exhibit and asked other visitors to share their secrets with Day to Day. One by one, they took her microphone off into a corner and whispered their private thoughts into Martina's recorder. She's woven the secrets together into a radio story for today's show.
