The farmers garage had been wrecked, siding torn away, insulation ripped from the building, and huge holes were smashed into the walls. Down through time myths develop, changing as they are told, retold as they change. That is what we are told. And we call them myths so that we do not have to face the implications such a realization might bring. The difference between myth and reality is that we can not experience a story.
Experience needs no proof.
It is an anchor in reality that enables a few to know where myth and reality interweave. To understand the nature of Sasquatch we must approach with an open mind.

Arvil, Joe and Vic know the truth, at least a small part of it. Yes, this is an unbelievable legend.
