Yesterday was a blue-sky winter day with mild temps but a strong wind. With plenty of sunshine I wanted to get out to enjoy the weather before the temperatures plummeted to below zero. A little before sunset I went to one of the area golf courses to get some exercise. As the sun was sinking in the western sky, the shadow lines grew long and longer across the unbroken snow. They seemed to stretch much further than the height of the trees, reaching as far to the east as possible. Winter is the prime season of beautiful, low-in-the-sky light, accentuated even more at daybreak and sunset.
