It’s not often that organizers of a major event find themselves with a perfect day, but the Greater Cornwall Chamber of Commerce did on Sunday, when they hosted the 52nd annual Cornwall Fall Festival on Main St. There were food and craft vendors, businesses, civic and service organizations, student-led booths, live music, demonstrations by dance and other groups, and, most of all, people, people, people out enjoying the offerings. Chamber President Scott Teresi called the day “a remarkable success.”
