I'm really digging on this willow tree. It sits along the road on my way to work. I've been waiting on a foggy morning to try this picture because of all the clutter that would be in the background - though this morning might have been a bit too foggy.
It gets it's unique flat-sided shape from growing up right beside of a house. That house was recently torn down exposing the flat side of the tree to view. There are no limbs with leaves covering the trunk and the branches on the flat side which makes the great contrast between the black of the branches and the grays of the limbs with leaves.
