We'll know how far we've gone once the ocean stops and we see Los Angeles set on fire by streetlights carlights spotlights from the passenger window.
We'll know how far we've gone once we see the giant orange chasm, the blistering white snowtop mountains and the crystal azure rivers from the passenger window.
We'll know how far we've gone when we see the amber waves of grain that I grew up singing about whispering in the Nebraska wind and see the capital building busting out of the fields.
We'll know we're home when the plane touches solid ground.
