INTERNATIONAL: While most of Latin America celebrates Labor Day on May 1, the rural town of Otumba, Mexico, dedicates the holiday to their hard-working donkeys.

In the 16th-century rural town in the state of Mexico, donkeys are kings for a day as residents and visitors celebrate their "burros".

Thousands of families turned out for the traditional Donkey Day to attend donkey races, polo matches, and a costume competition.

Spectators fawned over dozens of donkeys dressed from head to hoof in a wide variety of costumes such as Mexican television characters.

Farmer Agustin Franco who participated with his donkey in the costume competition is thankful for the hard work of his donkey. He said that the donkey is good and holy to him and helps him a lot, especially with financial alleviation and transportation.

The origins of Mexico's Donkey Festival are said to be traced back some sixty years ago, Otumba residents who relied heavily on donkeys decided they deserved their own day of honor.
