Huge lines of people, kids in tow, are waiting to get into the Smithsonian's National Museum of Natural History, the world's second-most visited museum.

Right inside the lobby, a cast of the skull of the new Tyrannosaurus rex the museum just acquired is stopping visitors dead in their tracks.

"We wanted to get up here before the exhibit for the dinosaurs closed," says Crystal Epley, who took a three-hour trip from Broadway, Va., to bring her son, John.

When Mexican artist Diego Rivera was commissioned in 1932 to do a mural in the middle of Manhattan's Rockefeller Center, some might have wondered whether industrialist tycoon John D. Rockefeller Jr. knew what he was getting into.

In 1934, the legendary artist's work was chiseled off the wall.

Now, in Washington, D.C., the Mexican Cultural Institute has mounted a show that tells what happened to Rivera's mural.

Megan Yurko is small, but she's a big name in barrel racing. And the 16-year-old is on track to be crowned the world's top cowgirl barrel racer at the upcoming International Professional Rodeo Association's finals in Oklahoma City.

Just under 4-foot-10, Megan depends on her 1,200-pound filly Beea in a sport where the fastest rider around three barrels in a cloverleaf pattern wins.

"The thrill of it all is awesome," Megan says.

Seventeen-year-old Tonisha Owens stared wide-eyed at the faded script on an 1854 letter. It was once carried by another 17-year-old — a slave named Frances. The letter was written by a plantation owner's wife to a slave dealer, saying that she needed to sell her chambermaid to pay for horses. But Frances didn't know how to read or write, and didn't know what she carried.

"She does not know she is to be sold. I couldn't tell her," the letter reads. "I own all her family and the leave taking would be so distressing that I could not."

Once again, the long-standing controversy over the name of the Washington Redskins is in the news. In May, 10 members of Congress sent a letter to the team's owner and several others urging a name change.

There's hardly an adult anywhere in the world who wouldn't recognize at least some of the music of Motown.

The R&B label changed the course of music in the United States and made household names of Diana Ross, Stevie Wonder and The Jackson 5. Now, the man who created Motown — Berry Gordy — is headed to Broadway to tell his version of how it all began.
