Roperchick, we are in Southwest Louisiana.
Kitten_Val, As I was taking the pictures (with my zoom lense) I noticed the marks. I put the camera down and went to check the horse. He had definitely been ridden. It is hard to tell from the far off pictures, but when I got to the horse, I could see where the saddle and girth had been. And, Jake is a pinto arabian and his markings are a light grey, so from far off, he just looks dirty lol.
I think that I may know who rode him. The couple down the road have the husbands kids every other week during the summer. They were here this week. I know that the woman use to have a stallion (but she couldn't control and got rid of him) that she kept in a pasture that is to the side of our back pasture. She did have a saddle at that time. These kids are not bad kids and I don't want to go accusing anyone because they are good neighbors. We will just watch and make sure that it doesn't happen again.
