Spanish Mustang
A living symbol of the "Old West". Tragically seen as an invasion species, and an "enemy" to ranchers. They are frequently rounded up, and sold for whatever purpose. Today they come is every color seen in horses, though some are only speculated like pearl. I differentiate American from Spanish due to differences in bloodlines, and physical appears. Americans tend to have an influence of various domesticated stock [including draught horses] and have lost a lot of the "look" of their Spanish ancestors while Spanish have been isolated for centuries way from others and has developed as an individual "breed" with distinct sub strains.
