Reo has a series of videos available on Youtube
This one shows him on a Utah mountaintop, and you can hear the vocalizations and wood knocking he describes. He is also flanked, and has small stones thrown at him (though we don't see those):
I don't expect anyone to actually watch the entire hour plus episode, but even if you're a skeptic -- like 99% of the population -- you'll at least find the scenery Edenic.
Here's one which describes his journey from skeptic to believer to actual field researcher who's had encounters with the creature. I particularly liked this one because he describes so well how he'd been unthinkingly dismissive at first, just like most people, but then, as he did more and more research on it, how it gradually dawned on him that the creature is real:
One of the reasons I find Reo credible is that he's so self-deprecating. He freely admits to having ADD, he's honest about his own (fearful) reactions upon encountering them, he admits he might be wrong about various things, he says his own brother is a far better tracker, and he even admits that he may eventually lose enthusiasm for the hunt.
But in the meantime, he's obviously got a passion for the subject, and there's something very appealing about his boyish enthusiasm.
These videos, by the way, are far, far better than that TV show Finding Bigfoot, which has become an embarrassment. Reo's explanation for why the show doesn't work: they expect the sasquatch to come to them, despite all of their TV lights and camera crews and yelling and banging about. Reo shows how to go to them. Reo also explains why direct line of vision sightings are hard to obtain.
You're welcome to laugh at me for being a believer, but at least give the videos a try before you do.
Update, 6/12/16: Unfortunately, Reo has just taken down most of his videos. Evidently some of his viewers had followed his trails, found his locations, and even posted routes to get there on the internet, and a few people had even stalked him. He briefly put up a video up explaining all of this, and now has even taken that one down.
