Since this forum is not exactly at the cutting edge of the business, let me help you boys out with this little problem that you are creating. Bigfoot are not like anything else that you have ever heard of or could possibly imagine. For starters, they communicate telepathically so they can read your mind like an open book. Secondly, there are millions of them. You can't find them because they are interdimensional. Look it up in your dikshunnery. You will then need interdimensional bullets for your interdimensional rifle. Don't know how to make them? Don't feel bad because nobody else does either. And one more thing. They are supernatural people, who can appear behind you with no warning whatsoever, and slap their hands together to collapse your skull into a very flat and messy and boney sandwich. And do it all before you can say, "uh, oh"! The problem that tribal officers have with them is that, the officers suddenly and inexplicable pass out for about a half hour, when caught out in the open and in the vicinity of one. They got off lucky. But hunters that are out deliberately going after them with guns, will not all be so lucky. Some will not come back, nor will their bodies ever be found.
On the other hand, if you choose to make peace with the Bigfoot and not hunt or shoot at them, then they will let you live to go home to your families. Indian tribes leave food in order to keep the Bigfoot friendly. You should seriously consider that method, because, YOU KNOW NOT OF WHAT YOU ARE MESSING WITH!
