Trinity Johnson reaches out to put a ball down a slinky while on a horse named Foss Wednesday, Nov. 14, 2018, at Rising Stars Therapeutic Riding Center southwest of Twin Falls, Idaho. Riding has built up Trinity's physical strength and coordination and has helped her to focus and follow two-step directions, her mother said. At first, Trinity needed "sidewalkers" to support her in the saddle, but today she rides solo.
