Ann, his wife, who is a dressage rider and owner of a very talented mare by the name of Rafalca.  When I worked at the US Equestrian Federation, I had talked with Ann once or twice on the phone about entering her horse at Oldenburg and other European CDIs..  Her trainer, German born Jan Ebeling, had planned on taking the horse to Europe to give her some exposure to indoor shows in the fall. I remember it was hinging upon how Mitt did in the primaries during his Presidential run in 2008.  Gorgeous horse that has the talent to make a team I recall Klaus Balkenhol, the then US National Coach for Dressage say.  They seem to be well on their way since in 2011 they were the highest placed US combination in the World Cup Final in Leipzig (GER) and were later chosen to represent the US at prestigious CDIO Aachen (GER).
