When I was growing up I had a red and white cow with a heart on her forehead, I called her Valentine. I also had a buckskin Quarter Horse named Abner who had a perfect white heart on his forehead as well.
I like the first one, except with positions reversed for me and Eric. I also like the one with the horse grazing, and the couple beside him. I think we could recreate that one with Cassie! She loves to eat!
