The "Mark" on a mustangs neck, is the identification given to him when he has been captured from a round up. Using the international Alpha Angle System, the freeze mark identifies the Registrant Organization, the animals birth year, and its identification number. The mark is typically unseen, unless the horse is galloping and his mane flows in the wind revealing it. Like the mustang, all are "marked" in some way. The outside forces that exist in everyone's lives, society, circumstance, environment, whether animal or human are challenges we are all subject to. I think we are all the same, in that way.
