I had a friend hiking out west someplace. He said he got an uneasy feeling and turned to see a mountain lion following him. He said the only thing he could think to do was call here kitty, kitty ,kitty. Luckily the "kitty" ran off.
Of all of the "wilde beasties" out there, mountain lions give me the willies the most. They are the only ones that will actually hunt a human. I have read numerous stories about turkey hunters doing what they do best - sitting still and sounding like prey being surprised by mountain lions.
MB had a chilling blog last year that started out "At 2AM I heard the lion cough"
Another story I read had to do with a Dad and son out deer hunting, only to spy a lion a couple of hundred yards off. They hightailed it back to the pickup, and returned next day with a whole team of hunters. They found lion tracks leading up to where they had left the pickup the day before - the lion had followed them all the way back to the pickup.
