Walking, ideally, is a state in which the mind, the body, and the world are aligned.

The language of commerce has been engineered to describe the overt purpose of a thing, but cannot encompass fringe benefits or peripheral pleasures. It weighs the obvious against what in its terms are incomprehensible. When I drive from here to there, speed, privacy, control, and safety are easy to claim. When I walk, what happens is more vague, more ambiguous-and in many circumstances much richer. I am out in the world. It's exercise, though not so quantifiably as on a treadmill in a gym with a digital readout.

I grew up with landscape as a recourse, with the possibility of exiting the horizontal realm of social relations for a vertical alignment with earth and sky, matter and spirit. Vast open spaces speak best to this craving, the spaces I myself first found in the desert and then in the western grasslands.

I walk wherever my errands take me.

When I think about, say, 1995, or whever the last moment was before most of us were on the internet and had mobile phones, it seems like a hundred years ago. ... Time passed in fairly large units, or at least not in milliseconds and constant updates. A few hours wasn't such a long time to go between moments of contact with your work, your people or your trivia.

Space--as landscape, terrain, spectacle, experience--has vanished.

For me, childhood roaming was what developed self-reliance, a sense of direction and adventure, imagination, a will to explore, to be able to get a little lost and then figure out the way back.
