Look for a future Sunday page on mustangs. Their status is controversial. Their heritage is not native, but linked to horses introduced by Spanish colonists. They are formally known as “feral”, not “wild.” This distinction carries a fair bit of baggage. Regular roundups are carried out by federal agencies and done to maintain a quality of life for the horses that roam freely. Captured horses are normally sold to private parties. We’ll see if Mark Trail actually deals with any of the issues and nuances of mustangs and horse management in this adventure.
