Trail is judged on the horses' ability to cleanly, quickly and willingly follow a pattern while maneuvering through, over and around obstacles. A collegiate judging team coach discusses requirements and rules the rider must follow and shows how to assign individual and overall scores and placings. Three runs are narrated as viewers watch horses try to complete the pattern with the least numbers of faults. A supplement is included. Collaborator: Don Topliff, Ph.D., West Texas A&M University.
