Time for some informal survey work. This weekend I was preparing some soil and I found a dowell that I had previously drilled a hole in and inserted a wire....like some telepone poles I once purchased. I guess I had used it to help prop up some plant a while back (like two years) Aside from being weathered grey, it still survived.
It was one of those "square dowells" one can get at Wal*Mart. I then, as a quick almost unplanned project...build a crude fence out of the same materials.
Question...how long do your treated and untreated wood structures normally last?
I don't intend for that fence to last long (pics soon), but its simple, construction means it can be rebuild with minimal effort.
