100+ acres for a backyard I treat as if it was my front yard, I put signs up, but if someone tore them down and stepped foot on the property and used every excuse in the book, I am sure that if I felt threatened the law would probably rule in my favor if I chose to protect myself if I am the last one standing. Always need to find out the property situation. Ofcourse, this is the far end of what I want, and they want, but just an example of what happens when people think that since anything without a NO is a GO, there are dangers. Life, jobs, rulings. I do put signs up to keep people away, not so much if it is legally my responsibility. Someone coming to the house to ask access to the river is a much appreciated gesture that usually goes over well- to me, or anyone. Sneaking on is not tolerated or smart. Last thing we want to do is be a part of the problem with access. Bad apples make things tough. Locally, 1200-1400+ pound Angus bulls do not care about signs and work 24/7 to protect "their" property for apparent fun We used to have a steelhead fishing shack on our property that the old boys (born in the 1800's!!!) would walk down and plunk, would always stop at the house on the first fishing trip of the year to ask about the cow situation. Smart guys ! Reason why they were old fisherman! The first fish of the year usually was offered to the landowner as well, I recall. A nice gesture. Miss them. People respecting each other, living in peace !
