While splitting a Post Oak today, it cracked open and I was surprised by the color inside. Inside near the center was an old staple and some nails. Wondering how old this tree was, I counted about 90 rings, the tree in the picture is about 12” in diameter. Post Oaks are very slow growers, and can live to 300 years. With the staple and nails being so close to the center of the log I'm guessing they were driven in about 70 years ago, around 1950. This was 4 years before I was born, back in the time of my parents. Stuff like this fascinates me.
