Read the references... I'm over your "I know what you are saying, but I'm going to keep ignoring what it means" position. You are citing opinion, I'm citing legal precedent. One has weight in a legal discussion, the other does not. In the ocean case listed, it was not required for the city to warn about something simply because 'some people may not know about it'. In prior wild animal cases, again, there is no standard I've found that says "you must inform the public about mother nature because they are from out of town" and no case I've found has successfully used the "well OTHER people know, but WE didn't" as foundation for needing to warn against wild animals in their natural state.
Instead of repeating yourself ad naseum... maybe funnel that energy into finding some rulings that support your train of thought. It will be far more convincing then you simply repeating it over and over.
