No problem Joey I know you wouldn't lie to me. But those were installed in a tidal marsh, right? Seriously though, were they in a wet area? Overhead irrigation or drip? Clay soil? And it seems obvious they were buried up top the adjustment screw on the knuckle. I think I even see some rust on that stainless screw though... what would that tell you? Oh, and if it was in a lawn all bets are off.
