Yard fences and land enclosures typically have a gate or other door structure that requires some sort of hinge, latch and looks different in overall appearance from the rest of the structure (just as the front door of a house appears different from the outer wall). Presented here is a simple mechanism by which any part of commonly used fences can be implemented as a fence opening. When closed, it appears as a continuous fence. However, when implementing the teaching herein, the space between any two fence posts can become a fence opening.
