Saskatchewan farmer went to drag a bale out for the cows. Freezing rain a week prior had that bale frozen down hard. He had a chain with a slip hook around the bale. Tried just pulling but not enough traction, so he backed up a bit and took a bit of a run at it. Chain broke. He said he looked for the hook for 15 minutes in the snow. Finally just tied the chain and got the bale moved. Had to cut and remove the bale twine and put the tractor away. -25F out. Came in the house and his wife yelled to get down, someone is shooting. She was cowering behind a chair and the picture window was smashed. He found the hook on the floor behind the couch and a dent in the wall. Wife must have been hiding for a half hour.
