This was taken in West Sumatra, Indonesia. Every 2 or 3 months local people held a cow contest festival named "Pacu Jawi". A jockey which is actually a younger farmer will ride the 2 cows. Not 'regular' cows but trained cows that able to running fast and straight in a muddy field. That is main requirement for the winner. No animal hurt. And they run only 50 m.
In mid April of 2012,....the festival will be held again.!
You could flight to Jakarta, and proceed with flight to Padang, West Sumatra.!
