My son's place has a circular drive that passes around the house, down a bit of a hill, around the back of the barn and then returns to the road. Veiw of the lower section from the house is mostly obstructed by the barn.
A few years ago, my DiL spotted the nose of a car peaking out from behind the barn where they process their firewood for the season -- in broad daylight. When my son investigated, he found the owner had skipped the whole offer stage and was loading up the trunk. "I was going to come up to the house to pay you once I was loaded." Yeah, right. My son made him unload and restack it all. He's too nice, I would have called the cops and had him charged.
I wonder how long it had been going on for?
He needs a CCTV camera covering that blind spot.
