As much as it pains me to say this, I found out he's right the hard way. We were dove hunting on the river several years ago. we got there by boat and thought if we hunted out of the boat we were legal. Landowner came and told us to get off his property and that he owned and paid taxes to the center of the river. We left and called game warden who verified this. As long as we weren't touching the bottom we were legal...except for the moving boat thing. Live and learn but I sure don't like it!
