The lyrics are very geographical in nature too:
Who can imagine the scale of the forces
That pushed this old mountain range up in the sky?
Tectonic creation, erosion, mutation;
Somethin' to pleasure God's eye.
The world is a wonder of lightnin' and thunder,
And green of the ground as we fall from the sky.
The old and new faces, the tribes and the races...
Thousands of places to try.
There's also the track with Mark Knopfler 'Sailing to Philadepelphia' about Mason and Dixon who surveyed earlier America, producing the Mason-Dixon line: the cultural divide between the Northern and Southern United States.
