That is the 64,000 dollar question to which I don't have the answer.

A neighbor has a "fence" made from ceder which is all but fallen down. He is at least in his 70's. My guess is that the fence was put up to hold in some horses on a small bit of pasture he has. I think the kids moved out and he got rid of the horses years ago. So 20-30 years maybe? But the fence looks like it has been down for at least a decade. I have seen other fences that look to be newer and while not falling down the sap wood has rotted and the fences don't look that good. Some of the posts look like you could walk up to them and push them over.
I would love to use the wood I have and save money. But I also don't want to be redoing fence posts in a few years either. I would rather do it right and be done. Most of the fences in my area are all PT SYP even though there is plenty of red cedar around.
Never met the neighbor but I do wave at him when I see him. I'll try to stop and talk to him about the fence.
Later,
Dan
