This is a buffalo ranch near Hartsel, Colorado. There was quite a herd, but these couple were the closest. ( Yes, I do know the two in the back can technically be considered "horses" )
I used Paint Shop Pro's "Auto" setting to enhance this image while I was cropping and resizing, and it warmed the image up a lot. I like the way it looks, but doesn't match my memory. I'm thinking about changing it back.
