I have a homesickness for a country that isn't mine...the steppes, the solitude, the eternal snows and big skies up there haunt me. One remains permanently engulfed in the silence where only the wind sings, in the solitudes almost naked of greenery, the chaos of fantastic rocks, dizzying peaks and horizons of blinding light.

No man can live this life and emerge unchanged. He will carry, however faint, the imprint of the desert, the brand which marks the nomad; and he will have within him the yearning to return, weak or insistent according to his nature. For this cruel land can cast a spell which no temperate clime can match.

-George Santayana

The world - this shadow of the soul, or other me - lies wide around. Its attractions are the keys which unlock my thoughts and make me acquainted with myself. I run eagerly into this resounding tumult.
-Emerson

Canada & USA.

Nature is ever at work building and pulling down, creating and destroying, keeping everything whirling and flowing, allowing no rest but in rhythmical motion, chasing everything in endless song out of one beautiful form into another.
-John Muir
