In the Laguna I saw some barbed wire fences, and many of them were quite rusty - or at least their posts were.
This one looks pretty good - no rust as far as I can see -, but I think that was the only one.
Lichen took over this post - and what is the barbed wire doing anyway?
The rust here has such a deep color - I really like it.
However, I like the close-ups of the barbed wire best - like this "vegetarian" one.
