Thank you. The additional information is interesting, and also perplexing.

What I'm perplexed about is this: who gives a flying fig about some nearly invisible symbolic boundary lines? Why are people so offended?

I respect the Orthodox Jews but, truth be told, it wouldn't make any difference to me if it was Hindus, Mormons or Santeria. It's an invisible boundary line that helps innocent, blameless, inoffensive people have a little more freedom of movement and action on the Sabbath.

Seriously, have at it. What's not to like?

Some people are offended by the people putting up the boundry, unfortunately. Anything different give them an issue to criticize. An Eruv, Kosher food, Sabbath observance, the Talmud, they’re all targets at times. Has nothing to do with the Eruv itself, which in most cases is completely invisible.
