I certainly understand that approach and know many share it but I respectfully disagree. Short of an unambiguous sighting, almost any sasquatch activity can be dismissed as human activity, as our ardent skeptics are always eager to point out. To lean is not to claim certainty, and one shouldn't feel shame for later deciding their leaning was in the wrong direction. Leaning towards a conclusion informs our investigative efforts.
Leaning doesn't require evidence; experience can be much more conclusive than a print in the mud. When a series of knocks leads me directly to a structure, and I never see the source of the knocks? I'm not leaning human. I have very little doubt about their presence in the Sidney Yates area.
My leaning on the UoC structures isn't nearly as strong, but it is based on a number of trains of thought that I've explained at length. To be honest, my gut reaction to these structures has been the strongest force, and the circumstances making humans less likely in my mind has only served to reinforce an intuitive leaning. Without that intuitive response, I wouldn't have explored Sidney Yates, and I wouldn't have learned anything. The same thing happened at a near-suburban trail in Colorado. The first hike was nothing but a weird feeling about the crow calls. The second hike began with clear knocks. That led to regular visits, a number of structures, innumerable knocks and small vocals, one very close encounter, and a possible glimpse.
I've come to think of sasquatch as two phenomena: there's the way sasquatch and humans approach one another; and there's the way humans approach one another about sasquatch. The latter is (still!) fraught with fear and negativity, and it causes people to be extremely conservative in their thinking. Dismissal has almost become standard protocol.
For their part, sasquatch deal with humans in shades of subtlety. They challenge us to observe, to notice. When you meet your own observations with undue dismissal, you're only slowing your progress.
People want this to be like some sort of CSI-meets-physical-anthropology type of science, and for me, the results of that approach speak for themselves. It helps that I'm not out to prove anything to anyone, not even myself, I'm only in it to follow things where they lead me, to try to learn, to try to meet them, maybe one day to befriend them. Fosey and Goodall laid the groundwork for the proper approach, and I say it's proper because it's the approach that gets results. They're not results that prove, but they're results that inform and instruct. In a lot of ways, they're repeatable with a high degree of consistency! You get results this way for the simple reason that this is how they want to be approached, and it's the only way they're willing to give us anything.
