Yep I said arrested , and yes I had someone taken to jail for repeated trespassing . Nothing much of came of it in the end but the individual who kept crossing my fence stopped after that. Depending on where you are in the state people don't tend to pay much attention to posted property especially if they are life long residents.
In deep SE Oklahoma where I was born and raised, if you're not from there you will never be. Outsiders often end up having issues when they buy property. Or they used to at a very minimum when they would run afoul of the locals.
SW OK is every bit as bad or worse.
The property I bought had been owned by the family since 1912. I was the outsider, though my family has been here since 1911. Dad left after getting married and though I "grew up" here, never went to school here. Dad moved back when he retired. I moved and bought my property 20 years ago. I am still an "outsider", even to neighbors I have known for 60 years.
Getting to know and backing up Sheriff and GW, having video evidence, marking your property is about the best you can do.
Azzhats will be azzhats. You just gotta teach them "Homie don't play."
