People of all faiths are invited to 2 of the 3 day events
That's odd... when I showed up all of the attendants and the people in the administration office were very suspicious of me even though I had done nothing other than show up. They even assigned a guy to follow me around.
When I asked them why they said that it was very unusual for non-JWs to show up.
It would appear as though the article was a blatant lie and placed there for no reason other than PR.
