I’m pretty sure you guys both have it wrong. My understanding after last year is that your fishing partner for the tourney CAN be your witness. No reason to haul a fish around the lake looking for a witness when you have your fishing partner standing right next to you. If you fish the tourney solo, well, then you will have to go looking for a witness.
You guys are not the only ones confused by this rule. I know many people who fish the tourney who thought they had to go looking for a witness too. Quite a few fish were killed on a certain lake last year during this metro tourney as a result of bad fish handling. I would contact Paul Hartman directly for specific questions related to the tourney. I personally don’t fish the tourney, not into tournament fishing. Just have some friends who fish it and that was my understanding from what they told me. Hopefully the rules will be explained better this year. Good luck.
