RE: Mountain Lion
I had the same thing on my the property I was hinting behind my parents house two years ago. My parents saw it several times and As my dad would work in his garden after dark more than once he sould shine a spotlight at the pines behind the house and it would be sitting there 30 yards from him just watching. Dad wasn't scared because they are much more scared of us then we are of them. But it is still intimadating hearing that scream they let out right before dawn.
The deer though never even flinched we killed several and saw deer every day almost.
