Total poppycock........no legitimate concrete evidence has ever been found. Do you realize how much food a creature of that size would have to eat, and what does it eat and how does it go about killing large game small game to survive? For the species to have survived for this long, there would have to be allot of them out there consistently producing offspring. They can't be compared to a bear except for their size, and do they hibernate as well? No evidence of Sasquatch shit loads has been found, no fur.......no bones.....no skulls...... and the reason is because they don't exist. The undiscovered species are in the ocean, now I fully believe there are undiscovered monsters lurking in the deep. Now ancient aliens on the other-hand, that shit is for real IMHO.
