I had a black bear put its paw on my shoulder while I lay on the ground one night in Yosemite Valley in 1975. Scared the livin' bejeezus outta me.
The stink of its breath as it huffed over my face is something I'll never forget.
I was holding a hunting knife in my hand at the time, thinking "Do I?" / "Don't I"...and apparently "Don't I" was the right decision as it eventually walked off and left us.
The rangers said, (the next day), that they were tracking that animal to be destroyed as it had attacked some backpackers in the area the day before.
