Okay, when I was younger, and we still lived in Cleveland, the drive to my grandparents house in Chicago took 6+ hours. So the trek out there, (they lived in Alsip, near Chicago) was always a pretty big event. Anyway, for a number of years, I had this recurring dream (sometimes it was nightmareish, but never that bad) involving this long car trip. The basic idea was that in order to make it to their house, we had to cross a very, very long, narrow bridge that crossed over a giant gaping chasm. As I was afraid of heights, and of bridges at that time, this was not something I was jazzed about. Anyway, this bridge coming up is just what the dream bridge looked like (only the drea bridge was much bigger, obviously.)
