The Marshfield Fair is the premier event for Plymouth County 4-H members and young people from across New England. The Marshfield Fair offers open youth participation for kids ages 5-19 exhibiting livestock shows, equine events, dog shows and other agriculture opportunities. Young people play an active role participating at the fair including offering demonstrations, interacting with fairgoers, care and maintenance of the barns, and fair planning.
Youngsters learn valuable life skills through raising and showing animals including responsibility for others, public speaking, leadership, and community service. 4-H members and others also gain experience in animal science, local agriculture and volunteer experience.
The Marshfield Agricultural and Horticultural Society presents many awards for excellence in scholarship, livestock, agriculture, and country craftsmanship. Among these is the Cave Canem Challenge Cup, honoring longtime Plympton resident Rita LaPointe, volunteer leader, teacher, and friend of 4-H young people. It is awarded to the Junior or Senior 4-H dog exhibitor who earns the highest total combined score in both Marshfield Fair Dog Shows.
