Ronald Reagan’s casket, with horses

Ronald Reagan's casket is led by a military honor guard up Constitution Avenue to the U.S. Capitol, where it lay in state. This was in Washington DC, on June 11, 2004. At first we thought that the horse at far left is the traditional riderless horse, usually with boots reversed in the stirrups to indicate a "fallen soldier." But now we think that must be one of the horses yoked to the caisson carrying Reagan's casket. A riderless horse, named Sgt. York, *did* accompany Ronald Reagan's funeral procession and must be out of frame here.
