Hey Diog yes it was your comment where I picked up on this nonsense. I was really surprised by this. The elders in our hall who fly fish have been doing so for a good 20 years so would have expected there to be some talk about this at some point.
Your comment was the first I ever heard of this.
I was also told the surf story but never really believed it. Saying that I always had nightmares about demons in my room and nights where I couldn't even go to sleep for fear of them when I was a child. This cult really messes with people doesn't it!!!
