MENDOTA - A flock of geese meander along the shore while others enjoy a swim in Lake Mendota during a warm, sun-splashed late summer day. The countdown is on for the final days of summer 2020 as the first day of Autumn is Tuesday, Sept. 22. The September equinox marks the moment the Sun crosses the celestial equator – the imaginary line in the sky above the Earth’s equator – from north to south. The Sun shines directly on the Equator and the length of day and night is nearly equal. (Reporter photo)
