I appear to be too late on the Poll, but I'll add my two cents..
First, I'll have to discount Any & all Supernatural explanations.
No offense to those who are supernaturally minded.. I just don't believe in the stuff.. I don't look down upon folks with different beliefs.
Is there Room for a Breeding Population of 7 foot tall Homonids in the Paciffic Northwest, Swamps of the Southeast and whatever other territory the Sasquatch, Yeti, Skunk Ape, etc.. have been sighted?
Yes, I think So.
Is it POSSIBLE
that a 7 foot tall, Intelligent & Skilled Homonid could avoid detection by Humans if He/she detected them FIRST?
(Is is possible that a 7-foot homonid could detect a human First, by sound, smell, etc..?)
That said, I have to remain on the fence on the whole "Yes/No" Issue and say "maybe" simply because Films & Footprints can be faked (And are faked very frequently.. Ever read the story of the Boy who Cried Wolf?)
The Best Film evidence in existance is the Patterson Film, and sorry, it's just not convincing either way..
It's a damned good suit.. or it's a Big, Ugly Furry Girl.
Both sit equal in Plausibility to me..
