If you’re young, male and you live in the city, how do you prove yourself in the most materially comfortable country on earth? How do you show courage, daring, skill, strength? How do you prove you’re a man? If you’re a Masai Tribesman in Africa you kill a lion. If you’re an Aborigine boy, you go on walkabout, if you live in Dogtown, Los Angeles you ride a skateboard.
