Alfonso Romo founded Mexico's Studbook La Silla to develop the ultimate jumping horse. While it's not a breed, La Silla has its own registry to ensure bloodlines and to help promote La Silla-bred horses in competition. The appearance of Colombia's Sancha at this year's Olympic Games speaks to the studbook's success.
