Horseless Horse and Horse Knowledge, unit HS140, is for youth who may not have a horse or pony of their own but want to learn about horses. Horse Riding, unit 141, introduces basic riding skills and styles. (Because a member's knowledge may be at a different level from his or her riding skills, a member may sign up for both units 140 and 141, and unit 140 will not be counted against his or her project total count.)
