Two years ago a forester began cutting and he was obviously going to run over everything in his path with huge equipment. So I tied ribbons on the rock piles and asked him to not run over them. I acknowledged it wasn't my property but
he would respect why the rock piles were important. He said he would try his best, as it was difficult to see from the top of his big equipment. I dared not go back until today, 2years later.
He hand tried to give the more important piles a miss.
