That's a big'un! Thanks for sharing. Many years ago A buddy and I were grabbing frogs in a slough in the delta. We noticed an old abandoned limb line moving and figured a fish was foul hooked. It was nighttime of course and when I pulled it up and first saw the head I thought it was a stump. The hook from the line was hung in the turtles foot. It was about the same size as the one in your picture. We cut the line and let it go and have often wondered how old it was and if it's still alive. I've heard tales of giant turtles found with old musket balls embedded in their shells, amazing a creature can live to be that age.
