I went to Greyreef for the first time, and was wondering if the river below greyreef dam is the famous big fish part? Or is the river between the dams is part of big fish area. When I was fishing between the dams, this guide told me I was trespassing, I said I didn't see a sign. The guy says see there and points to a metal sign painted red (18"x18"), I said there is nothing on it. He gets pissed and tells me to go back to Colorado, I get pissed and tell him if he needs help to spell the words I will. Have you ever run into the red sign thing?
