Sorry to mention this, but summer is drawing towards its endpoint. After that, the chills of autumn and then the wilds of winter can wreak havoc on fences that are not as secure or as strong as they once were.
You might have board and post fencing that was installed a generation ago. Or chain link fencing to help protect part of a commercial property. Even wrought iron fencing, which seems as if it should last forever, can become a little weaker after standing up bravely to the passing of many winters, so often harsh, here in Colorado.
