Saying hunters cover every inch of territory is again absolutely a stupid comment. Most hunters don't go bush whacking, and when they do they typically go to known places again and again. Even so, there are certainly many reports from hunters who say they have seen a bigfoot, and were way too scared to even think about shooting one. I've been hunting plenty of times in Washington State myself. The hunters are everywhere comment is such a joke - you might see a good number of hunters on a day driving around, but stop anywhere and you pretty much don't see anyone. Deer are in high numbers around the state, right? Many deer hunters I know (and my entire family is full of them) gets skunked unless they're willing to put some serious time in in a season. You're also forgetting that there are numerous places in the state where hunting is not allowed, and that sasquatches actively hide.
With all that hunting you've done, have you ever come across a bear carcass? I didn't think so. But you know they're out there. Aside from Yellowstone, I've only seen bears twice with all my hours logged in the woods, and once was just a fleeting glimpse of one as he ran off into the bush.
