Bruce Davidson held his son, Buck, after winning his second World Championship on Sept. 17, 1978. Davidson rode Might Tango in the first World Three Day Event held at the Kentucky Horse Park. Four years earlier, he won the World Championship at Burghley in England. After 1978, the event became an annual competition, held permanently at the Horse Park. Buck Davidson also became a top equestrian. In March, he was the No. 5-ranked rider on the world listings. Photo by Christy Porter | Staff
