The fine old game of flinging shoes over wires or trees. A shoe tree, not to be confused with the shoe-preservation device of the same name, is a tree or a powerline pole or other wooden object that has been festooned with old shoes.
Shoe trees are generally located alongside a major local thoroughfare, and may have a theme, such as high-heeled shoes. There are currently at least seventy-six such shoe trees in the United States, and an undetermined number elsewhere. There have been many explanations why this happens, but no one really knows for sure. They do make an interesting, though weird, artistic statement.
