``Why do large numbers of hikers venture into the wet, wild woods with biting insects and stinging nettles, on trails lined with roots and studded with rocks? There is something different and deeply appealing about hiking in the out-of-doors. The wilder and more beautiful the land, the better the hiking. Clearly, these experiences are spiritual. It is the deep, but bright, secret of hiking. Spiritual experience is essential to our well being, so hiking remains popular.''
