Cedar fences...

I found fences made from freshly cut cedar too! I want to put a fence like this around my backyard so it was exciting to find these.
This fence was "doubled" - there were cedar posts on both sides of the iron rebar supports.



The "single" fence had cedar posts wired to only one side of the rebar. The posts that hold the fence up are iron pipe filled with concrete. It looks like they used galvanized wire to tie the cedar to the rebar.

I wonder how long these fences will last before the iron parts rust through? Have any of you constructed similar fences?
