Perhaps walking is best imagined as an 'indicator species,' to use an ecologist's term. An indicator species signifies the health of an ecosystem, and its endangerment or diminishment can be an early warning sign of systemic trouble. Walking is an indicator species for various kinds of freedom and pleasures: free time, free and alluring space, and unhindered bodies.

I think that fear of the mob, the expectation that people, particularly poor and nonwhite people become mobs almost automatically in the absence of coercive authority, is inculcated by the media, the movies, and politicians.

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 bigness of the world is redemption. Despair compresses you into a small space, and a depression is literally a hollow in the ground. To dig deeper into the self, to go underground, is sometimes necessary, but so is the other route of getting out of yourself, into the larger world, into the openness in which you need not clutch your story and your troubles so tightly to your chest.
