Hello! Several people have made suggestions in Southern California, and there is certainly a high concentration of dressage trainers here. The new West Coast Dressage festival will be starting soon, and that might also be an option to view a lot of nice horses in one place.
There is one in particular I know of for sale, 8YO currently scoring in the 70’s at PSG and correctly trained by a German Bereiter who rides regularly with Christine Traurig. Clients who come to this barn often remark at how correct and through the horses are. Happy shopping!
