I’ve never seen mustangs in the wild out west, but I did get to see a herd rescued by a genuine rescue…they took on a whole HERD, and were in the process of buying large acreage in north of Florida to keep them on so they could live together . Till they were moved the horses were in a smaller (normal size ) paddock. I went to see them, and standing around, looked like small coarse scrappy horses. But when they moved, they moved as one, and it was extraordinary. Not moving as domestic horses do when domestic horses move as a herd or group.
When I say these mustangs moved together as one, it was as if all their feet were synchronized to the exact same footfalls…which is why they also go by the name, “ghost horses”… a whole herd galloping with hardly a sound, almost disappearing as they went by, hard to explain…more like a fluid river of silvery coats than horses. It really is a crime to separate them from herds and make them lead silly domesticated lives because we America can’t manage our ranges properly.
