Brooklyn is well represented at Stone Barns Center’s sixth annual Harvest Fest on October 3, featuring BK bluegrass band Astrograss, Mast Brothers chocolate, and Van Leeuwen Ice Cream. A Berkshire pig roast, hayrides, and farmer demos, of course, are worth the extra travel time. Tickets range from $10 to $30 for kids and adults, and you’ll need cash for food. [Stone Barns Center]
