We know the things we know because they've been taught to us, sometimes directly, sometimes obliquely, legend-by-osmosis. The things we don't know are things we've never heard bout - whatever has been left out of the conversation, struck from the record, or simply never even considered. We sometimes have to unlearn these early teachings, or at least learn that some additional facts inhabit the legends we've been passed down like heirlooms, each as solid as a land mass and casting long shadows, just like the Buttes themselves.
