Larger then life night life

I was driving home the night before deer hunting opener in 2010.  As I was turning off the gravel road onto the main tarred road going to my home, my lights swept the field and I saw what I thought was a deer in the field.  But then the animal stood up and a tail as long as the animal itself appeared.  I knew I was looking at a large Mountain Lion. Since this experience I have heard that my neighbors have had similar experiences.  I am more aware of the my surroundings since then.
