Las Vegas suggests that the thirst for places, for cities and gardens and wilderness, is unslaked, that people will still seek out the experience of wandering about in the open air to examine the architecture, the spectacles, and the stuff for sale, will still hanker after surprises and strangers. That the city as a whole is one of the most pedestrian-unfriendly places in the world suggests something of the problems to be faced, but that its attraction is a pedestrian oasis suggests the possibility of recovering the spaces in which walking is viable.

There are those who receive as birthright an adequate or at least unquestioned sense of self and those who set out to reinvent themselves, for survival or for satisfaction, and travel far. Some people inherit values and practices as a house they inhabit; some of us have to burn down that house, find our own ground, build from scratch, even as a psychological metamorphosis.

No one is born a writer; literacy is a peculiar mode of being, but I was all about stories from a very early age, before reading.

Sense of place is the sixth sense, an internal compass and map made by memory and spatial perception together.

The fight for free space-for wilderness and for public space-must be accompanied by a fight for free time to spend wandering in that space. Otherwise the individual imagination will be bulldozed over for the chain-store outlets of consumer appetite, true-crime titillations, and celebrity crises.

For many years, I have been moved by the blue at the far edge of what can be seen, that color of horizons, of remote mountain ranges, of anything far away. The color of that distance is the color of an emotion, the color of solitude and of desire, the color of there seen from here, the color of where you are not. And the color of where you can never go.

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.
