I spent a couple of weeks in 1995 solo camping on the Eastern edge of the Grand Canyon National Park and had a mountain lion check me out every night. I had some borrowed night vision goggles and could see her sitting on the next hill looking at me. I found new tracks around the area every day. I did build a barrier of sorts with branches around my bed down area, but she never bothered me. Saw her once during daylight hours with a cub. There were so many mule deer, elk and antelope around that I did not present a more appetizing meal.

I got up close and personal with a lot of wildlife on that trip, it was excellent.
