...[Cabeza de Vaca] ceased to be lost not by returning but by turning into something else. - Rebecca Solnit

This is the strange life of books that you enter along as a writer, mapping an unknown territory that arises as you travel. If you succeed in the voyage, others enter after, one at a time, also alone, but in communion with your imagination, traversing your route. Books are solitudes where we meet.

Everyone has stories of the small coincidence by which their parents met or their grandmother was saved from fire or their grandfather from the grenade, of the choice made by the most whimsical means that led to everything else, whether you're blessed or cursed or both. Trace it back far enough and this very moment in your life becomes a rare species, the result of a strange evolution, a butterfly that should already be extinct and survives by the inexplicabilities we call coincidence. The word is often used to mean the accidental but literally means to fall together. The patterns of our lives come from those things that do not drift apart but move together for a little while, like dancers.

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.
