Ever since a small boy, I have loved just to look at the mountains, to see them in different lights and from different angles, to feel their rough rock under my fingers and the breath of the winds against my feet... I am in love with the mountains.

If adventure has a final and all-embracing motive, it is surely this: we go out because it is our nature to go out, to climb mountains, and to paddle rivers, to fly to the planets and plunge into the depths of the oceans... When man ceases to do these things, he is no longer man.
