I have some land in SE Oklahoma the going rule that I’ve been told is if you cross an open gate leave it open and if you cross a closed gate close it behind you

I have some land in SE Oklahoma the going rule that I’ve been told is if you cross an open gate leave it open and if you cross a closed gate close it behind you. However, I still make it a point to meet and shake hands with the owners of the land I cross. I live in Texas and, especially near the border with Mexico, you’re putting your life in danger trespassing on land, no matter how remote, without permission.
