In Edmonton, winter arrives all at once. Just a week ago the river valley was bathed in gold - The sun would set just as I was walking home from work, turning the sky marmalade and the North Saskatchewan river saffron with the reflection of the sun and autumn leaves that only turn yellow.

Now it's twilight when I cross the bridge. The sky is gray, and the river valley is a black and white photograph. There is only snow or silhouette against snow.
