We are still working on clearing out the ruins of the rotted out posts, all three of which were emphatically dead at the ground line. Getting the posts out was enough to put paid to one more section of fence as well.
All of the sections of fence have been demolished, nails removed, and the still-useful pickets separated from the ones that are rather the worse for the wear.
Sam will be coming back tomorrow to help me figure out how to sink the posts. If we can just get the posts in the ground and the cross beams up, nailing the pickets is going to be easy by comparison.
Sam has wondered if it would be easier to dig out the old concrete sleeves. I suspect that this is not the case. I hope that I am right...
