“After his European tour, Dylan returned to New York, but the pressures on him continued to increase. His publisher was demanding a finished manuscript of the poem/novel Tarantula. Manager Albert Grossman had already scheduled an extensive summer/fall concert tour. On July 29, 1966, while Dylan rode his Triumph 500 motorcycle in Woodstock, New York, its brakes locked, throwing him to the ground. Though the extent of his injuries was never fully disclosed, it was confirmed that he indeed broke his neck. Dylan took advantage of his extended convalescence to escape the pressures of stardom: "When I had that motorcycle accident ... I woke up and caught my senses, I realized that I was just workin' for all these leeches. And I really didn't want to do that.”
