Well, I have always wanted to get a few horses and name them unique names. Like Alpo or Elmer. Something that would catch your ear and be a way to start a conversation. Not saying that I think that lightly of horses, I am serious. You can strike up some good conversation over animals.
She's two years old and doesn't have a name yet? Hmm. If she were a boat, I'd remind you that it's bad luck to change the name of a boat.. but since she's a horse, how about Justine.. Justine from Lostine..
