I've been intrigued by the variety of methods people use to keep horses in one place - that is, variations on tying or confining them. The styles vary with the lifestyle and landscape, and each method has advantages and disadvantages. Some are based on the obvious necessities of the environment: for example if trees are hard to find, then wooden fences or buildings won't be your first choice; if you move around a lot, nomad-style, then you will probably use something lightweight and moveable, like a tether, to keep your horse nearby. Depending on where you live, some of these methods may seem very normal, and others quite unusual!
