The Diamond-McNabb Ranch Horse Sale invites visitors to experience authentic ranch life, Wyoming scenery, and generations of horsemanship at the 18th annual sale.
For nearly two decades, the Diamond-McNabb Ranch Horse Sale has drawn horsemen, families, and Western lifestyle enthusiasts to the rolling mountains of Wyoming for more than just a day in the sale ring. The sale is built on the long-standing partnership between Diamond Land & Livestock, owned by the Diemer-True family, and the horsemanship program of renowned trainer Ken McNabb. Forged by generations of ranching, horse training, and shared values, the event reflects a legacy shaped by real ranch work, where the rhythm of daily life on a working ranch shapes the way horses are trained.
Set against the rolling country that surrounds the Powderhorn Ranch, this gathering is not just a place for buyers to see the top-notch training that produces quality horses the program is known for. It has grown into a place where visitors can step into that world for a weekend and experience it for themselves.
“The sale has always been about more than buying a horse,” said Ken McNabb, horse trainer and co-founder of the sale. “It’s about helping people really discover the horseman within themselves and giving them a chance to experience what real horsemanship and ranch life are all about.”
One past customer described the weekend as something that stays with you long after the final horse leaves the arena. “Seeing the horses and the way they connect with their riders was absolutely incredible,” the customer shared. “You can just tell their training comes from real ranch work, and when you see it in person, it just makes you appreciate that bond between the horse and the rider in a whole new way.”
Those who make the trip to the 18th annual Spring Sale on June 6, 2026, will find that the weekend unfolds at the pace of ranch life. With an all-new Friday sale preview, time will be spent watching horses work live cattle and over real obstacles, visiting with riders and trainers, and experiencing the breathtaking landscape of Wyoming. The expanded Friday preview offers a closer look at the sale horses before the evening settles into a barbecue dinner, live music, and conversation that carries on long after the arena quiets down.
By the end of sale day, the weekend feels less like a live auction and more like a reunion. At its heart, it's a weekend built around a shared respect for good horses, open country, and the traditions that keep both alive.
For many who return each year, the Diamond-McNabb Ranch Horse Sale is not just about the horses that pass through the ring, but about the chance to experience a way of life shaped by generations of partnership between horse, rider, and ranch. In a time when the Western lifestyle often feels distant, a weekend at the Powderhorn Ranch is a reminder that those traditions still endure, keeping the heartbeat and legacy of the West strong.
