I've hit a few deer and have had few run into the side of my trucks.
The closest calls I've had was a horse that reared up in dense fog. Had he not reared I would have smoked him.
The other was broad daylight traveling from Glendive, MT to Fort Peck reservoir on a camping trip. Came over a rise doing about 80 mph in the GF's little car and there was a 2000 lb black angus bull standing broadside in the driving lane.
I missed him by inches and he gave ME a dirty look.
