CHIANG RAI - MARCH 12 2006: The matches are held in all manner of buildings, from shanty shacks to upscale arenas. In the larger arenas, the winning purses can be $10,000 US or more, with bets raising the stakes even higher. Bird Flu caused the banning of cock fights in 2005, but a persistent movement of Thai's claiming the social significance of the sport and a reduction in Bird Flu cases has allowed the fights to resume.
