"Travel takes control away from us, exposing our weakest points. We are acutely aware of our vulnerability. We are naive, unaccustomed, unacquainted, unversed. We are ignorant, roaming in the darkness of the unfamiliar. We are lonely, lost, disoriented. Travel pushes us across the chasm. We are moved to explore the mysterious, to confront our fear, to venture beyond the challenging, cryptic crevasses of our path."
