"Came to Santa Cruz: 1968. Abraham was a professor at Princeton University in his early 30s when a UCSC recruiter visited him. He had developed an interest in psychedelic culture and mystical experience, but had no interest in relocating to California. 'I accepted the free airline ticket to see friends,' he said. His interview didn't go well, he said. But before leaving, he went to find a friend at the Barn in Scotts Valley, where "I saw the musicians playing inside large metal sculptures, psychedelic paintings on the wall and 300 people stoned on LSD dancing to the music.' Soon after, he changed his thinking: 'I was interested in Santa Cruz the town, not Santa Cruz the university. But it was a job, so I accepted it.'"
