When we moved to Oak Hill, this item made of pipe was laying on the ground in the weeds. Later, I found another pipe sticking up out of the ground in another location. I realized the piece in the photo was supposed to be on top of the pipe in the ground. It turns on the pipe that sticks out of the ground. There are remnants of a fence nearby; evidently this was a "gate" that the cows couldn't get through, but a human could easily push it open even though his/her hands were full, like a turnstyle. Pretty ingenious, isn't it?
