Now infamous in cryptozoology circles is an eldery fellow named Mr. Mike who told his friends he has been seeing Bigfoot (and family) hanging out in his backyard. According to those close to him, Mr. Mike really believes this. He has convinced many people with his stories that there is something happening in his back yard.
But there are no pictures and no one else has ever seen them, which is causing many researchers to assume that his determination and confidence is due to a mental instability. We'll find out soon enough, however, as video equipment has been put in place to figure this out. (More on that investigation at Cryptomundo.)

I'm not buying it. I don't believe animals (even cryptids) can comprehend technology and I don't think their presence causes us to enter into a contract with them by which we are not allowed to film them. Animals don't act that way. Rodriguez says this has happened to him before which makes me think that this is really just a clever explanation to explain why he has no evidence for his claims. Saying that Mr. Mike's Bigfoot will not show up because of a camera is a convenient way to place his bets since it's unlikely it will yield any results.
Of course, introducing new people into an environment will usually scare away animals, so there's some truth in this, but a concealed camera put in place quietly should not cause a problem. In the past, cameras placed in the woods to look for Bigfoot have turned up pictures of deer and bears. This would mean that cameras do not deter wildlife and, as such, should not deter Bigfoot either. Rodriguez's statement makes it sound as if he thinks that Bigfoot is more aware of technology and would understand the media in the way a normal animal would not. That sounds very Hollywood, but it doesn't make much sense.
