I don’t need to quote Robert Frost. We all know that fences play a useful role in our society, especially in urban areas. But how to fence: that, my dear, is the question. To stain or not. Wood or metal. Let it rust. Paint it black. Criss cross apple sauce. Peek-a-boo cutouts. Open or opaque. Tall or small. Vertical or horizontal. Wood slats of narrow narrow narrow/wide wide wide, or wire mesh. DIY or architect-designed.
