If 'The Wild One' were filmed today, Marlon Brando and the Black Rebel Motorcycle Club would all have to wear helmets. I used to be afraid that when (Hells) Angels became movie stars and Cal the hero of the book, the bikerider would perish on the coffee tables of America. But now I think that this attention doesn't have the strength of reality of the people it aspires to know, and that as long as Harley-Davidsons are manufactured other bikeriders will appear, riding unknown and beautiful through Chicago, into the streets of Cicero.
