Bear Story and Another Lizard

I was hiking at night when I heard a ferocious bear bellowing. He was right ahead of me. I thought of camping for the night, but thought he might attack me. I made lots of noise so as not to surprise him. His bellowing became so loud and ferocious, I beat a hasty retreat back to my re-supply car via paved road. I later found out he was in a cage which I couldn't see at night.
