Just read the account for yourselves, this way I don't have to play middle man, sorry my Kindle app was on the fritz or I would have simply done this sooner and I guess I forgot it was a scarf...the creature was attached to Lori.
"One particularly poignant, and amusing, moment was when we tried to deceive the Big Guy, to see if we could draw him out of his lair and photograph him. We went up to the area where he lived, went about our business gathering samples, and on leaving, had Lori drop a scarf on the ground “accidentallyâ€. We then proceeded to a pre-scheduled spot on the road, high above the area, where we waited with a camera. The creature was not fooled though, and began banging vigorously while we were on the road.“The ******* knows exactly where we are!†I joked with Bryan, who also shook his head and laughed! “This is your last bloody chance, you had better **** well come out!†he shouted, We all fell about laughing. He was very bright indeed, and was clearly not going to be fooled or tricked into an appearance on camera!"
Here is some more and this predates the above and provides background
"If it is at all possible , the story now gets stranger. Fortunately it is all true, and was witnessed by Professor Sykes. After I got back in February, Professor Sykes gave me a call. He said that he was going to be in the USA, and was working with someone called Rhett in getting samples from potential Sasquatch for testing. He asked if he could meet Lori. Lori was delighted to accept, and volunteered to take Professor Sykes and Rhett up to the location. It was on that day that Professor Sykes was to have his own Sasquatch experience. Lori adopted the same methodology as she always does when approaching her area. She called out on approach, and the “Big Guy†responded, with his familiar knocking in response to Lori. Lori recounted how shocked Bryan was by his encounter, just like I had been. To quote from him: “I definitely heard knocking, it was subterranean, and was not caused by Lori.â€
More yet of Adam's first experience
"After we pitched our tents, Lori resolved to take me up to the area where she had her encounter with what she referred to as her ‘Big Guy’. We approached a fir tree, and Lori showed me where she had left apples for the creature , and how it had taken some. She took clear “before†and “after†pictures on her camera, so she was able to record any movement, and be sure of what, if anything, had been taken. After she had explained the background , she began calling out to the creature in the following manner: “Hello, are you there?†Her tone and manner were, in some ways, like a mother would speak to a small child: upbeat, positive, and coaxing, all at the same time. To my amazement, I began to hear a knocking sound in response to her voice! Lori spoke in an animated manner, “Oh,†she said in delight, “You are here!†and straight back came a “boom boom†thudding sound. I watched Lori’s feet ; she did not make the sound, it was quite clear . I also had the presence to check around the area, to see if there could be anyone hiding, and responding to these sounds. There wasn’t, but strangely, though, the ground did, underneath, feel hollow, and spongy I thought. I was amazed by this interaction, and was forced to draw the conclusion that whatever Lori was communicating with, was directly underground, by the tree, and that she had not faked it herself."
