Three mares grazed shoulder to shoulder across the Utah desert sage, moving with a quiet rhythm that only long familiarity creates. They weren't simply feeding together—they belonged to the same family band. Wild horses naturally organize themselves into small social groups, often called bands or harems, consisting of a dominant stallion, several mares, and their offspring. The mares form lasting social bonds while the stallion watches over the group and protects it from rival males. As I watched these three grazing so comfortably together, one title immediately came to mind. Sister Wives. It made me smile then, and it still does today.
