I appreciate all the comments, and thanks to Peggysue and Glamson for your treatments of the image. This was one of those times I missed having a built-in flash on the 5D...I would have popped it up for a little fill and catchlights.

The real problem was that I was shooting at the wrong time of the day, around 2pm...I either had shade or direct sunlight, and fences were in the background in nearly every shot.
