"We learn a place and how to visualize spatial relationships, as children, on foot and with imagination. Place and the scale of space must be measured against our bodies and their capabilities. A 'mile' was originally a Roman measure of one thousand paces. Automobile and airplane travel teaches us little that we can easily translate into a perception of space. To know that it takes six months to walk across Turtle Island/North America walking steadily but comfortably all day every day is to get some grasp of the distance. [...] I think many of us would consider it quite marvelous if we could set out on foot again, with a little inn or a clean camp available every ten or so miles and no threat from traffic, to travel across a large landscape – all of China, all of Europe. That's the way to see the world: in our own bodies." (pg. 98-99)
