"In English folklore, Jack Frost appears as an elfish creature who personifies crisp, cold, winter weather; a variant of Father Winter or Old Man Winter. Tradition holds Jack Frost responsible for leaving frosty crystals patterns on windows on cold mornings." http://en.wikipedia.org/wiki/Jack_Frost
Winters here in the Upper Goulburn leave mornings crisp and frosty.
Grass, fences, stock, animals, trees, leaves and infact everything outside is a photographers paradise.
Up early and camera firmly tucked under jacket you can take great photos of Jack Frosts' work.
