Have had several encounters with black bears, all ended peaceably, but I did get real concerned once. I was deer hunting and had a black bear walking down the trail I was hunting next to. I first saw him about 40 yrds away, slowly grabbed my gun, and got it ready, then stood up, bear looked right at me, and kept coming! I had the sights on his head and thought to myself, three steps and he's a goner, he took two and was coming down with the third when he turned and ran! I paced it off, he was 17 yards from me. Had one encounter with a grizzly in Glacier National Park, I was camping and treed a cub on the way to the bathroom, knew mom had to be close, I hightailed it back to the trailer!!! Grizzly encounters don't usually end well.
