I don't think they would harvest it JB given that

I don't think they would harvest it JB given that it may be ancient, they mentioned so in their FB post. It still would be pretty cool to see. I'm not much for diving myself but would perhaps make the effort to see such a thing.  Come to think of it, perhaps that picture is from Mobile, AL. I would hope that's not the case and that the pic is from somewhere where a concession could occur.
