Well as most of you, I've been on the fence most of my life as to cougars' existance in Ontario, specifically Northern On, where I am from. Hearing third part stories from someone's brother or cousin or what not who have seen them (most with little or no real world bush experience or species knowledge)... I'm more of a "Don't believe anything you hear and only half of what you see" kind of guy. I rarely believe things until I see them for myself.
I was harshly shoved off the fence this weekend.
Me and a good friend of mine, both Northern Ontario boys who grew up in the bush, were out hunting some grouse and walking some trails up 144 (between sudbury and the watershed) coming up to a crest in the trail heading around a corner and 30-40 feet in front of us was a full blown cougar. He took off into the bush at a high rate of speed. It was in broad daylight about 4pm on a sunny day. No, it wasn't a fisher, a lynx or a bobcat (I've see all of the above and have almost been attacked by a bobcat). I knew what I saw and when I looked over at my buddy, I was reassured by the look on his face as well. We did not get pictures as we saw it for a mere 2 seconds or so and equipeed only with a .410 and a bow, nedless to say we were not sticking around to examine for tracks.
Take it for what it's worth, I could really care less. However, this is my FIRST HAND account of what I saw with my own eyes making me a believer.
