My plans were brutally torn to shreds at Toronto airport by an American immigration official named (as I recall) McCullough. I had spent a week lecturing in Vancouver, at the University of British Columbia, and was now on my way to Oberlin College, Ohio, and, from there, to the University of California at Berkeley. I'd been an itinerant migrant worker for the past decade. It was a way of life I was used to and so, I believed, were the Americans. It was thus with a certain casualness that I placed my papers on the counter.
