Next things got a bit more serious as a larger bear came in to the bait. It was very aggressive and cleared the others out of the area very quickly. It wasn't a huge bear but it was the biggest I had seen and I started to seriously think about taking the shot. It meandered off without presenting a shot opportunity that I was comfortable with.
I decided that if it came back I would take the shot. Well within half an hour it was back once again clearing out the smaller bear off the bait. It chased a smaller bear at least 20 ft up a tree and made sure he new not to come back, we saw that smaller bear later on and he was limping, I guess it got a lickin'.
The aggressive bear came back and started to feed again. It stood up noticing another bear approaching and walked a few steps behind the barrels. My opportunity was starting me in the face, sting tight, full draw, back tension, release.
