Working on a story about the Wagon Wheel Ranch in Lometa, Texas, I had four chances to photograph mares and foals being moved through a pasture by the ranch's cowboys. It wasn't until the fourth try that I got an image I liked. However, the strange, dark spot on the foal's shoulder bugged me for a few days. Then I realized it was shadow of a flying grasshopper, visible above the young horse's hindquarters. I kinda like the shadow now.
