Famous quotes containing the word travel:
“For my part, I travel not to go anywhere, but to go. I travel for travels sake. The great affair is to move; to feel the needs and hitches of our life more nearly; to come down off this feather-bed of civilisation, and find the globe granite underfoot and strewn with cutting flints.”
—Robert Louis Stevenson (18501894)
