HE advice to Travis Bickle while standing outside the Belmore Cafeteria (Park Avenue South and 28th Street): “Look…you write a diary…right? You got a typewriter? Get one, get some typing paper and tap out a daily diary about your cabby life…not just the fares but your deepest thoughts…hates, fears, longings. And submit these pages to the Village Voice and the Soho Weekly News or some other weekly rag. Become a New York version of Charles Bukowski.”
