The appeal of the wild for me is its unpredictability. You have to develop an awareness, react fast, be resourceful and come up with a plan and act on it.

I miss him still today: his long, whiskery eyebrows, his huge hands and hugs, his warmth, his prayers, his stories, but above all his shining example of how to live and how to die.

All my life the only thing I've been good at has been climbing and throwing myself off big things.
