COMSOG, the Community Solar Greenhouse of Martha’s Vineyard, is continuing a 21-year tradition of celebrating the arrival of the fall season by welcoming Island residents and their families to its Fall Harvest Festival on Sunday, Sept. 30, from noon to 3 p.m. at the greenhouse off of New York avenue in Oak Bluffs.

There will be free soup courtesy of Linda Jean’s restaurant, music by the Vineyard Brass, spinning demonstrations, art and crafts from Vineyard artists, plants, jams, jellies and produce, fresh baked goods and many trifles and treasures. Plus, activities for the kids will go on throughout.

Just look for the yellow and green sign, next to Dick’s Bait and Tackle. Park across New York avenue at the church.
