Because stirring the pot is so much fun.....

Just for grins, let's assume that Bigfoot lives in Mt Rainier and in Olympic NP. Further, they are nocturnal, live in the forest, are smart enough to consciously avoid humans, and live in low densities. If one was out there and 100 m from the trail, would you see it? My point is that we actually visit/see a tiny fraction of the landscape. Just because a million folks visit the area doesn't mean that the whole area is searched/viewed.

Not saying they're out there, but that there are lots of places where we never really look.

Refer back to the effort Todd describes about chasing those BT is a small path of woods.
