Another fantastic three-day clinic with Mark Shaffer’s Mechanics N Motion! Always inspiring to spend time learning, riding, and improving alongside great people and horses. Huge thanks to everyone who helped make it a success at Maxson-Box Stables in Walla Walla, WA. Already looking forward to the next one!
