"They" say their are none around here in Middle TN. But I've been a hunter all my life and pay close attention to my surroundings. Back around 96' - 98' I came home the back way and about 150 yds. from my home a COUGAR jumped across the road in full stride about 20 yds. in front of me... stopped on the edge of the road for 1/2 second (less) and dived down into the deep ravine. I jumped out, looked and never saw it again. I still have never seen another since here.
Later that same year a guy I met owned a pasture about 1.5 miles away (as crow flies) and said he watch one walk right along his fence line, clear the fence and disappear. Same time frame as mine. He also never saw it again.
