Having the flu on an Oregon west side elk hunt cost me a nice bull one snowy day. Had hunted a lone bull for three days, sickern a dog, and couldn't locate his bed. Finally just too sick to keep hunting in the wet, dripping slush, so dropped my head in defeat and headed for the truck for the last time.
Yep, kicked him up at 70 yards, nice bull, no shot opportunity since I was dragging my rifle in the dirt!!!!
