I suppose I'm a stickler for semantics. If I offer you a bubblegum wrapper as evidence of bigfoot, it is **evidence**. It may not support the case, but it has still been presented as evidence so it IS evidence. Something being evidence has nothing to do with whether it is accepted, the only thing that matters is that it was offered. What follows (acceptance or rejection) is based on analysis of the item of evidence offered.
Stick structures ... in 5-1/2 decades in the woods, I've never seen one, not even in places where I've encountered bigfoot. I've seen two tree twists which I believe were caused by deep snow with an ice layer at the top creating a fulcrum about 5-1/2 feet above ground, then a snow mass sliding down that ice broke the trunk at the point where the ice fulcrum focused the force. And, of course, an epic amount of elk tree breaks, but the antler gouges through the bark are a dead giveaway.
The single weird thing that makes me wonder was this. I've mentioned the ridge where the BF counted coup on me by sneaking up on me and only gave himself away by farting at an inappropriate moment. It's one of my favorite, most successful places to kill BIG blacktail bucks. Starting maybe 200 yards further down that ridge, and going for probably a half mile, one day the evergreen huckleberry bows were woven ... nonstop line down the top of the ridge. Came back 1-2 days later and there was no weaving/braiding, none. Weirdest thing I ever saw. There was no evidence I could find for what caused it and no evidence later it'd ever happened. A puzzle.
