I ran to get this picture and I just love it. I love the angle of the horse, and how clearly you see his feet and legs against the dust road. I love the angle of the rider, and how he is tipping his hat. You can clearly see his huge rowel spur (ouch!). I did not do any cropping or photoshopping - this is right out of the camera. I considered cropping the right side out but it has the political signage, so for now it stays.
Here is a slightly altered version of the above photo. I still have to get my photoshop tutorial.
