. . . well into elementary school, there was a sign which really did dominate my life and this was the advertisement for my father’s company that he worked for my father’s company that he worked for—the Phillip’s 66 sign because many years of my life, many days of the week I would be driven right by that sign at least two or three times a day, ‘cause my mother would often drive my father to work in order to have the car for the day and then, drive back. And from our house to his office, the road passed directly under that sign. Now this was a huge electrical sign which was mounted very high in the air and was connected with a filling station. But it was a thing which absolutely fascinated me. And now of course since I’m up to the Sixth Dream, it will be the pivot for my Sixth Dream.
