This is interesting. I checked after the article, and see that where I live has at least 3 areas demarcated with an eruv. There are historical and documentary videos about them on Youtube. Apparently they're pretty expensive to maintain, and according to one that I watched, if someone isn't paid to monitor one, then you have to assume it is "not working" since they can easily be damaged by weather or utility repairs, etc. I've surely seen them around and thought nothing of it. I have a feeling that various "support wires" I've seen are exactly these.
