Hooo. That is high confidence. Do I recall correctly that you once took a shot at one with a duck gun?
Well, it would be more correctly stated that we took a shot at "something" but that incident needs to be put in perspective.
This was coastal SC ( no established bear population but factually a rogue bear does make it there every few years and gets popped by someone) but on the down side, I was a kid who at the time dont remember if I had ever even heard of BF then. ( this was like 72-73 ish) ( I do remember thinking it was a bear and at the time a BF never even entered our thought process)
It wasnt until several months later that the paper had a story of a BF sighting with tracks along the Pee Dee River ( maybe 10 miles from where we were) that BF even came into the picture as a possibility. At that time, I had never seen a bear in person ( other than a zoo) so had zero knowledge of how they sound or act in the wild. It didnt sound like any bear I've heard since and given the approximate sillouette, it didnt appear to be 4 legging it.
Also, it was at "stand to" so vision was still adjusting to daybreak and thick swamp foliage ( we never did get a clear unobstructed view)
Also, I didnt have the knowledge,experience etc I have this day ( coloring the event by the mindset of a young adult then the "fear factor" on top of that)
so, accounting for memory degradation, lack of any meaningful investigation et al with all things being equal- I'm comfortable with saying it could be either a bear or BF ( 50-50) simply because I'm not aware of any other animal ( real or imagined) of that size and speed and makes that howl.
That incident alone wouldnt make me a "believer" but it was coupled with #2
At that time I WAS an experienced observer, vet and had a team of like people who witnessed the same thing for an extended period of time. It also showed up in NV as well as thermals. This "thing" never went 4 legging and even stooped down like it was picking up stuff. We also has 2 size references ( deuce and trackless APC) to gauge realistically the approximate size ( somewhere between 7-8 feet max) and none of us thought it was anything BUT a "man" ( probably drunk or either hiding contraband on the range) until it went by the vehicles.
Its the combination of the 2 that take me to about 90% but in the same breath I state that my figure is meaningless as anything beyond my personal opinion because I dont have the first legitimate fact at my command and theres a realistic possibility ( even probability) that both were legitimate misidentifications and it was a bear and a tall dude.
Thats why you dont hear me whistling "woo" or take the typical stance. I acknowledge a strong probability of error in my assessments of my experiences.
