A man snaps a photo from his cellphone of a protest of nude farmers in downtown Mexico City, Mexico, Friday, April 21, 2006. In recent years, the protests from the group 400 Pueblos - who fight for land rights for poor farmers - have become an anual event for city residents, as the men and women from rural southern Mexico stand naked or nearly-naked along the city's busy avenues.
