BigFoot . Mothman ETC

I am watching a program about people who claim to have seen bigfoot or some sort of bipedal hairy conivorous animal in the forests of the USA .I am very skeptical because nearly every time they have all been armed and had mobile phones but none have caught a picture or shot one .One bloke and 2 of his friends reckon they were camping and he had the animal in his rifle sites for several seconds but never got a shot off yet he claims he was an experienced hunter .
I think they all have vivid imaginations or were drunk or on drugs or something .I know if I had an animal like that in my sites instinct would be shoot .The human instinct to kill or be killed would kick in .I certainly would not stand there looking through the site of a gun and just stand there .
They may have heard strange noises but seeing I think is bullshit .You cant tell me if your hunting and get something like that in your sites you wouldnt shoot .Self preservation would kick in .I think its a bit like the fishermans tale of ginormous fish that was nothing but average their all just tall tales .
