There is a fence that needs no posts, no post holes, and no concrete. It just zigzags.
The worm fence, also called a Virginia worm or snake fence, is built from split rails, most often about 10 feet long, stacked in a zigzag line. Where two stacks meet at an angle, the rails overlap and shorter cross pieces, around 6 to 6 and a half feet, are laid over the top to lock the corner. The weight of the rails does the work. There are no vertical posts at all.
That design had practical advantages. The fence could be moved to change field sizes, grazing areas, or property lines without new post holes or rotting posts left behind. In rocky ground or hard subsurface layers, where digging post holes was nearly impossible, it avoided the problem entirely. And the zigzag shape worked on irregular terrain where a straight fence line was awkward.
One point to keep in mind: the sources I used do not give how much timber a full fence needed, so I will not guess. What is clear is that it was a design built around a readily available material and the ability to pick it up and move it.
Have you ever seen one of these zigzag fences still standing?
