A jockey controls harnessed cows during a &#39;&#39;Pacu Jawi,&#39;&#39; a cow race, on November 17, 2012 in Batusangkar, Indonesia. The &#39;&#39;Pacu Jawi&#39;&#39; is held annually in muddy rice fields to celebrate the end of the harvest season. Jockeys grab the tails of the bulls and skate across the mud barefoot balancing on a wooden plank to show the strength of their bulls who are later auctioned to buyers.
