The only shot I got to take of agriculture, man plowing rice paddy with a water buffalo. In the next paddy a gas-powered cultivator was being used. The dense dotting of farm families working in rural fields reminded me of a demographic map--very different from the wide, unpopulated fields of the U.S.
