06 APRIL 2013 - SANPATONG, CHIANG MAI, THAILAND: Water buffalo for sale at the market in Sanpatong, Chiang Mai province, Thailand. The buffalo market in Sanpatong (also spelled San Patong) started as a weekly gathering of farmers and traders buying and selling water buffalo, the iconic beast of burden in Southeast Asia, more than 60 years ago and has grown into one of the largest weekend markets in northern Thailand. Buffalo and cattle are still a main focus of the market, but traders also buy and sell fighting cocks, food, clothes, home brew and patent medicines. PHOTO BY JACK KURTZ
