I saw a one antler moose while deer hunting in northern Minnesota long ago. For a while when I could not see much of it I thought it was the largest deer I would ever see.
We were sitting a few hundred yards away form each other and I heard the loudest crash....thinking he fell from his stand I was about top get down but I waited and heard it again. About 20 min later a big bull moose comes walking down the logging road I am not to far from. He was bedded between us (closer to my buddy) My buddy said it came within 10 yards of him!! He was headed into the swamp until by friend took a pic and the moose heard it and turned towards me. (we didn't have digital camera back then!)
It made our rain/soaked filled weekend camping and not seeing any deer. It was pretty cool to see.
We then went to a local bar after to watch the Packer game and no one believed us!! LOL
