When I am not in Mexico, I do live briefly and reluctantly in Southern Texas. I had a friend until he died, what you call a "good ole' boy."
He told me that in Texas, on the ranches, they did not feel obliged to mark it no trespassing. If it is your land, you know it. And, if it is not your land, you know it as well.
He told me it is simple, if it is not your land, don't go on it without permission. Period. if you do they may hold you at gun point in the dirt on your stomach for an hour or two waiting for the sheriff. I believed him.
He rented land years ago on the Laguna Seca Ranch north of McAllen. It has a very historic cemetery on it. He wanted to show me. Before we walked 100 feet through an open gate to the cemetery gate, we drove to the ranch headquarters to ask permission. The man there told us when the outer gate is open, respectful visitors may enter the cemetery.
It was an interesting visit. They put pictures on the tombstones. There was a woman, sister who raised him, of the deceased owner of the ranch at that time, she died many years ago, but there was a fresh photo of her. I don't know if those things are permanent or if they replace them from time to time. I never saw those photos in the North.
Here in rural Mexico private property is shown by two somethings protruding alongside the path or road. We have large concrete posts on both sides of our private street which crosses our property. We do permit everyone to cross our property on that private street because there is no other access for a number of people.
But, the concrete posts put them on notice not to park, or wreck things, etc.
A cousin said if you are following a path in the forest, and there are two sticks propped up beside the path, you have just been informed no trespassing. I suspect this is tradition or what we call common law, but am not sure.
