Result!When I took on this farm three years ago my top field was badly fenced so I renewed it. Fella with two sons and a dog kept cutting the fence, in two places, so he could take a short cut across my field to wherever. Blocked up his little path with logs, branches and tree trunks. He kept cutting the fence and pulled everything out onto the field. This happened about half a dozen times. Bought a nice trail camera and nailed it to a tree looking at fence.
Then nailed blown up stills from the video to the fence post showing him cutting fence and dragging out logs.
Also nailed note to fence saying "I know who you are now and so do the police"
Found pictures and note ripped into pieces and stamped into the mud.
He hasn't been back.
