Who could have known architects were that common-sensical! Best idea I’ve heard in ages.
I’ve seen first hand barbed wire strung to trees instead of posts that have over time become embedded deep within the tree trunk. I searched and found an old forgotten family cemetery in rural north Alabama where the last burial was in the 1950’s. The graves were overgrown with trees 10+” in diameter coming up through the graves. Most of the 60 or so graves in this heavily wooded cemetery have been lost to time, covered completely with growth.
