Some excellent shots this week. My pick is going to be for CLS, the path to the light. I have been over these a couple different times and always come back to that one. Excellent tones, colors and framing.

Excellent photo of the aurora Kari.
Brant, I have never seen more than one heron in a certain area and for you to catch them fighting, was awesome. That whole sequence you posted in the bird thread was crazy. Perfect exposure and light.
Stephen, that rainbow is incredible. You position to catch that just right along with the background is great.
