We have a number of bad posts here. For instance, there is one that is roughly 110 feet southwest of my front window. It's full of dry rot and is home to a nest of carpenter ants. It's all mossy on one side and has weird mushrooms growing off it. It has a crack at the bottom. Due to the crack, the dry rot, and the ants, it finally fell halfway over last week and this has caused our fence to sag badly in that section. I fear it may have to be replaced. Another 50 feet over was a perfectly good post...perfectly good until a visitor backed their car into it and knocked it down. It is now a bad post, because it's broken.

Does that help?
