Here's an old thread nearly identical to this one.
My post shows a newspaper delivery tube that I nailed to a tree across the ravine. It's a 'witness monument' above a corner stake that had just been placed by a pro surveyor. I intended it to be visible from our side so I could point it out to my family.
Grandma of that clan had just had a survey done as part of her estate planning, to clarify her intended inheritances of various parcels over there.
What I didn't post in that old thread was that a week after I climbed through the poison oak jungle in the ravine to nail that newspaper tube to the tree, I met the Black Sheep grandson of the clan over there. He insisted the property line was the stream in the bottom of the ravine and the far slope was his to run his 4-wheeler on. He insisted that my newspaper tube monument was down at the creek so the far slope was his. I discovered he had moved my monument within a week after I placed it.
I phoned the surveyor for verification then went and painted a 16 inch tall white band around the tree over there where my newspaper tube had been. After I described the grandson's dishonest act, and argument, to another neighbor, word got back to Grandma and he quit riding his 4-wheeler in my ravine. Several years later he was found dead in bed and everyone said they were sure that was from his drug habit. Everyone remaining in that clan is good decent folks, good neighbors.
And a little farther down in that thread. A
story I wrote about someone who sued the state over a property line issue and I was sent to hear his argument. The conclusion I wrote up was he had no loss, therefore his claim was pointless. I don't think he prevailed.
Actually that entire thread is interesting, for anyone interested in property surveys.
