We invite speakers with a wide range of expertise from Grey/Bruce and other parts of the province. These evenings are open to the public. The auditorium is open by 6:30. The meeting gets under way at 7:00, and may include brief announcements by other organizations as well as OSFN club activities, club business, social time, nature sightings and reports.
