MEXICO CITY -- More than 100,000 of our fans cheered for the Master of the 619 when he was featured atop a wrestling ring float in the city's annual Children's Day parade. The annual event takes place the Sunday before April 30, which is Mexico's Children's Day.

Rey Mysterio's appearance was the highlight of this year's parade, as many spectators wore Mysterio masks, T-shirts and held signs for the WWE Superstar. He was the most cheered for celebrity in the parade, and even had to stop signing autographs at one point because the crowd grew so large and the parade had to continue moving.

The Children's Day parade features television stars, pop singers, well-known athletes and role models that are popular among Mexican children. The festivities begin at the Chapultepec forest area, a popular Mexico City landmark for kids. It runs along the busy Reforma Avenue, passing by important landmarks such as the Mexican Independence Monument and the Torre Mayor, the tallest building in Latina America, finishing in downtown Mexico City.
