"For my part, I travel not to go anywhere, but to go; I travel for travel's sake. And to write about it afterwards, if only the public will be so condescending as to read. But the great affair is to move; to feel the needs and hitches of life a little more nearly; to get down off this feather bed of civilisation, and to find the globe granite underfoot and strewn with cutting flints." Robert Louis Stevenson, Travels with a Donkey in the Cevennes
