This year, Idaho on my first black bear hunt. Little bear stuck his head in the blind i was in from my right (the door didn't quite close all the way). I was busy watching the bait and felt his breath on my neck. First thought was "where is momma". He proceeded to come around front and we were eye to eye at about 2 feet. Cute little bugger, maybe 50 lbs, about the size of a labrador.
Several whitetail bucks come in close while turkey hunting. Some sniff and run, others sniff, huff and stomp like they're ready to fight.
Mostly, just coyotes and 1-2 yards while hunting. They usually get the shotgun if I'm hunting with a partner.
