Walk-about, vision-quest, spirit-walk, pilgrimage are journeys of discovery, first of this world, then of your inner and outer selves and ultimately of another world. The author of this book hiked thrice across Europe on El Camino de Santiago, and across America twice, Florida to Canada: once on a monstrously mountainy Appalachian Trail, once by a route of his own design: El Camino Americano, described within. All that after early retirement, he circled Earth on earth too, hiking where Great or Grand insisted: Grand Canyon to the Great Wall of China; Great Lakes to the greatest lake, Baikal in Siberia. On Grand Tour, the wanderer necessarily circled all of Ireland, every foot on foot. The wildest trek took the writer from agnostic to gnostic.
