I’ve always loved walking. I like the simplicity and freedom of it. No tying or troublesome equipment needed — just a serviceable pair of feet. Planes, trains, ships, cars, bikes, horses and donkeys all limit you in one way or another. With foot travel — barring walking on air and walking on water — you can go wherever you want, whenever you want. You don’t have to look at a timetable, you don’t have to wait for a ride, you don’t have to spend lots of money and you don’t have to buy loads of gear. All you have to do is point your feet to the north, south, east or west. Walking creates an intoxicating sense of possibility you don’t experience with any other form of locomotion . . .
