I used to hunt a really large ranch in central Wy a lot. On one boundry, it bordered a school section (section= 1 sq mile). there was another ranch on the other side that bordered the section on 3 sides, so it was totally surrounded by private prop. This ranch posted all 4 sides with No trespassing signs. The ranch owner I knew told me I could hunt it with his permission. I used to climb the fence and shot several nice deer & elk in it. One day the foreman of the other ranch challenged me and said he was calling the sheriff and have me arrested. I said go ahead, I have permission and showed him my tags signed by the owner I knew. He wasn't happy but backed off. Guess he knew we were right.Bottom line is you have to know what you can & can't do. If you have any doubt, call the state land div.
