I posted this on another thread but I'll post it here as well.
A few years ago a buddy and I had packed into the Buffalo Bill area in Plains, Montana. We were working down a revine that was a bottle neck with high walls on each side and thick brush on the bottom. The smell of a rotting carcass filled the air. After a brief argument who should go down the trail first, I lead the way. My budddy reasoned that since I had the pistol, I should lead, after offerring him my weapon and the lead, I proceeded upon his refusal. The brush was thick and there was bear scat everywhere, fresh too. My buddy hissed "Stop! Right there!" and he pointed. I lifted my loaded and ready .45 Auto and strained to see the bear. The brush exploded and I fired two rounds in self defense as the grouse cleared the brush and flew away. My buddy nearly fell over laughing, I, however, didn't think it was so funny.
