Day 04: Winter

Winter being my favourite season (bet you didn't know that *g*) finding a picture to fit was terribly difficult because I have so many beautiful pictures from which to choose.
After much thought I decided to opt for the really simple, but stunning picture of trees and a road duly blanketed in snow. It gives such a feeling of peace.
