My son and I went to see the new spotted foals that were born recently at the Stonewall Sporthorse breeding facility at the Rush Ranch near Fairfield, Calif. The horses are stunningly beautiful and since they are part draft horse, they are also big. We visited with Michael Muir, the breeder and founder of the Stonewall Sporthorse Registry, and I interviewed him for the story that I’m writing about the history of another horse ranch.
