In 1983 Triangle Sales Co, Inc. moved its operation to Shawnee, Oklahoma. From that point, sales were conducted exclusively in Oklahoma and the sale sight was moved from the Oklahoma City Fairgrounds to the Heart Of Oklahoma Exposition Center in Shawnee.

Triangle is one of the primary lessees of the Heart of Oklahoma Exposition Center in Shawnee, Oklahoma. Over the past several years this facility has expanded with the needs of the company.

The Expo Center is a modern facility which boasts over 168,000 square feet under one roof, making it a great place to market horses in all weather conditions. All sections of the barn are heated. The sale arena is also air conditioned in the summer months. All consignments are stalled in separate box stalls and the facility is able to comfortably house 750 horses.

John Bowling, cofounder of the company passed away in January of 1994. The company continues to successfully operate under the guidance of Cindy Bowling Garner and her husband Mike Garner.
