‟Living constantly among streets and houses induces a sense of enclosure, of short-range sight. Whenever I return from the moors, I feel a lightness up behind my eyes, as though my vision has been opened out by twenty degrees to either side. A region of uninterrupted space is not only a convenient metaphor for freedom and openness, it can sometimes bring those feelings fiercely on.”

(Robert MacFarlane: The Wild Places)
