Only time I have been truly scared in the woods was in college. My girlfriend's at the time parents had a small hunting cabin. We were there one night "hanging out" by the fire when we heard what sounded kind of like a person scream in the field behind us. I grabbed the really dim flashlight we had and shined it in the field and could see two green eyes. I asked her if she wanted to see a bobcat up close. I started slowly walking towards the eyes with her following me trying to convince me to turn around and go back. I got to within 20 yards or so and I started getting a little nervous because I expected the bobcat to run and the eyes seemed like they were too high off the ground. A few more steps and I made out the figure of a large cat with a long tail. I told my girlfriend to slowly back up into the cabin. I didn't tell her until we were inside that it was a mountain lion and it had let is walk up to within 20 yards of it. We stayed in the cabin for the rest of the night.
