This year’s annual Corn Festival, being held Sept. 21 and 22, will return to its roots: celebrating the harvest and traditions of New England, said event organizer Chris Jacobs. Visitors will see wood-carving, blacksmithing, spinning, quilting, basket-making, and other demonstrations, and dine on corn chowder and other corn-based treats. There will be live musical entertainment, children’s activities, and hay rides. Anyone interested in being a part of this year’s festival should contact Jacobs at email@example.com. Admission for members of the South Shore Natural Science Center, where the event is being held, is $6 for children and $8 for adults. For nonmembers, it’s $8 for children and $10 for adults. The annual Harvest Moon dinner, which kicks off the weekend celebration, will be held Sept. 19 at the Natural Science Center and includes a five-course meal of locally sourced food, with wine pairings.
