"That is the charm of a map. It represents the other side of the horizon where everything is possible. It has the magic of anticipation without the toil and sweat of realization. The greatest romance ever written pales before the possibilities of adventure that lie in the faint blue trails from sea to sea. The perfect journey is never finished, the goal is always just across the next river, round the shoulder of the next mountain. There is always one more track to follow, one more mirage to explore. Achievement is the price which the wanderer pays for the right to venture."
