We just caught the end of a fishing show on TV (The Fishin Hole with Jerry McKinnis). He was chatting on camera while building some kind of fence post I've never seen before: He had taken wire fence and bent it around in a circle (like you would do if you were going to put compost in it) He was filling the wire with loose rocks. He set those out in the field like fence posts. It had rails between the posts, that went into the stone "post". Unfortunately, I couldn't see how deep the "posts" were, if they were in the ground at all. I also couldn't see if there was a support of some kind inside the stone tube. Does anyone know what he was doing?
