Very nice series.
A technical point; trespassing on private property is always illegal. If land is not posted and you are caught by the landowner, he/she must file a complaint for you to be charged with trespassing. However, if the land is posted, a county sheriff can arrest you and you will be automatically charged with trespassing without the participation of the landowner. So the effect is that if land is posted, you are unable to apologize to the landowner and ask forgiveness. That option has been taken off the table by the posting. I caught a guy on my land filling a water tank on the back of his truck from my well. I caught another guy grazing his cattle in my pasture. There is no limit to what people will try when they think they can get away with it. My land is now posted. The guy who grazed his cattle claimed he was renting my neighbor's pasture and his cattle got through the fence. I might have believed him. Later he was caught loading hay (the big round 1,100 pound bales) on his trailer. That can't be an accident. End of rant.
