No moutain lions here, and for bear, you have to go to the Smokey Mountains where it is illeagal to hunt. Sorry, but once you're "set up" in your hunting stand, (not just me, but anyone) you will see and hear anything as large as those two animals you mentioned long before they know you are there. I think you've watched to many "people in the woods" movies. Make no mistake about it. A person with a bow or a gun in the wild IS the top preditor.Yes, and the heartpounding excitement when a grizzly bear or mountain lion springs up from behind or above the hunter and "surprise" the hunter becomes the hunted.
