Watch Cineb. Each year, horse trainers journey to Reno, Nevada to compete for one of the most challenging equestrian championships in the world.

For the world, it means another year of survival for a culture at risk and the continued refinement of the art of vaquero-style horsemanship that dates back to the first Spanish missions in California.
