This is a rather feeble barbed wire fence. You can see one of the posts (or spreaders) is broken off near the ground, but the wire is still taut, so something holds it up.
But for me, the real fence is all the cactus behind the barbed wire. All kinds of prickly plants: ocotillo, barrel cactus, prickly pear, cholla and probably more.
It wouldn’t be the fence that kept me from crossing this land, it would be the plants!
This fence and cacti are near Sahuarita, Arizona and cover hundreds of acres of land.
Linked this to Friday Fences – you can see quite a variety there.
