Seven-year-old Sofia Petrov is from Hungary. She says she likes the circus school.

SOFIA PETROV: "It is fun. I get to meet a lot of new people from all over the world."

The newest Ringling Brothers show is called "Dragons." "Dragons" is the company's one hundred forty-second show. It brings together talent from eighteen countries. Acrobat Paulo Dos Santos is from Brazil. He recently celebrated the birthday of his two sons before the show.

PAULO DOS SANTOS: "This moment is so good because everybody is coming. I am so happy because I see, you see I have friends here and my children too. We stay together, party together, show together, everything."

At each stop, the performers and their families get a chance to go into town and explore. They travel locally either by bus or in their own cars, which are also carried on the train.

One day there might be a chance to have fun at an amusement park, like Hershey Park in Pennsylvania. Another day they might explore a landmark like the Grand Canyon in Arizona. For ringmaster Jonathan Iverson, the circus train is like a city without a postal code.

JONATHAN IVERSON: "This is home. The backyard changes. Today's backyard has Hershey Park. Tomorrow's backyard has the Grand Canyon. That is the magic of it. But we are always home no matter where we are, we are always home."

SHIRLEY GRIFFITH: In some places, the canyon walls are more than a kilometer deep. Far below is the dark, twisting line of the Colorado River.

On the other side, sunshine lights up the rock walls in red, orange and gold. The bright colors are the result of minerals in the rocks.

Their appearance changes endlessly -- with the light, the time of year and the weather. At sunset, when the sun has moved across the sky, the canyon walls give up their fiery reds and golds. They take on quieter colors of blue, purple, and green.

JUNE SIMMS: Hundreds of rocky points rise from the bottom of the Grand Canyon. Some are very tall.

Looking at the Grand Canyon is like looking back in time. Forty million years ago, the Colorado River began cutting through the area.
