They say that seeing is believing. But sometimes it's a question of what you're willing to believe.

As Vince Gerasole WBBM-TV reports on The Early Show, in a week centering on the spiritual, when millions from around the world flocked to Rome as the new pope was picked, hundreds in Chicago have been taking part in their own pilgrimage, a procession to the site of what they call a miracle.

"I think, with everything happening in the world, maybe it's a sign that everybody should just start praying," says Patricia Villadonga.

What is "it?"

Beneath the busy Kennedy Expressway, the faithful keep coming, day and night, just to be near what they believe is a viaduct vision of the Virgin Mary.

"I don't know how to explain it. but it's something beautiful. It really is," says Olga Davila.

They see the image holding a rosary, hands clasped in prayer.

A commuter on her way home from work first spotted the freeway fresco over the weekend.

Inspectors said it was probably just a stain from last winter's snow and road salt.

But as word got out, so many came that traffic was blocked. Barricades and understanding officers, though, turned the street into a shrine of sorts. That left plenty of time and space for reflection.

Not everyone is moved by the image that's come to be called "Our Lady of the Underpass."

One girl remarked, "They say there's a girl holding a rosary, but I can't see no one."

Yet others leave convinced of divine intervention, even if it's under the interstate.

Highway workers were all set to wash away the image, but since so many have come to see it, it's unlikely the anything will happen to the image anytime soon.

Chimp Can't Kick Cigs
# Charlie The Chimp At South African Zoo Addicted

Apr 22, 2005 12:46 am US/Eastern
(CBS) It might be an obvious saying, but this is the perfect example of "monkey see, monkey do." When a chimpanzee started behaving in a uniquely human way, zookeepers knew they had a problem on their hands.

Charley, the smoking chimp picked smoking cigarettes after he picked up a pack of cigarettes thrown to him by the allegedly smarter humans who come to see him at a South African zoo.

"Charley's picked up the habit from watching people. He learns from mimicry," Daryl Barnes of the Bloemfontein Zoo told CBS News Correspondent Richard Schlesinger.

Adults should know better than to encourage smoking — children certainly do.

"Do you think it's a good thing that people give the monkey cigarettes?" Schlesinger asked one little girl.

"No," she replied.

"What will happen?

"They will get sick."

Everybody gets a laugh watching Charley smoke, like a hairy scary star of an old tough guy film. But the people who care for him and care about him are not amused. Zookeepers have asked people to stop offering Charley cigarettes.

"He's getting older," said zookeeper Barnes. "And as he gets older, if he smokes, it'll damage his lungs."

But Charley is addicted to cigarettes.

And, according to the zoo, "he acts like a naughty schoolboy" and hides his cigarettes when his handlers happen by. So now the zoo has to help a monkey go cold turkey — resist the temptations of humans — and get him to understand that "monkey see, monkey do" isn't as good a philosophy as "do what I say, not what I do."
