Moon Rider is a 7 year old Thoroughbred gelding who had a successful racing career under the name Hunted Guy. When his racing career ended, he was adopted by a new owner who fell madly in love with him. When she could no longer keep him, he came to live at the sanctuary. In spite of a neuromuscular disorder, Moon Rider gets along quite nicely roaming around the pasture with his new girlfriend, Lavender, who always manages to get his attention.
