The mistake was a natural one. The elevators, which were busy even in the dead of night, were today clogged with catatonic parents from New Jersey clutching beanbag chairs and giant stuffed animals. Fortunately (he thought), adjacent to each elevator was an entirely unused stairwell.
Casimir discovered shortly afterward that in the lower floors of the Plex all stairwell doors locked automatically from the outside. I discovered it myself at about the same time. Unlike Casimir I had been a the Plex for ten days, but I had spent them typing up notes for my classes, It is unwise to prepare two courses in ten days, and I knew it. I hadn't gotten to it until the last minute, for various reasons, and so I'd spent ten days sitting there in my bicycling shorts, drinking beer, typing, and sweating monumentally in the fetid Plex air. So my first exposure to the Plex and its people really came that afternoon, when I wandered out into the elevator lobby and punched the buttons. The desperate Tylenol-charged throngs in the elevators did not budge when the doors opened, because they couldn't. They stared at me as though I were Son of Godzilla, which I was used to, and I stared at them and tried to figure out how they got that way, and the doors clunked shut. I discovered the stairways, and once I got below the bottom of the tower and into the lower levels, I also found that I was locked in.
For fifteen minutes I followed dimly lit stairs and corridors smelling of graffiti solvent and superfluous floor wax, helplessly following the paths that students would take if the Plex ever had to be evacuated. Through little windows in the locked doors I peered out of this twilight zone and into the different zones of the Plex-- Cafeteria, Union, gymnasia, offices-- but my only choice was to follow the corridors, knowing they would dump me into the ghetto outside. At last I turned a corner and saw the wall glistening with noisy grey outside light. At the end of the line, a metal door swung silently in the breeze, emblazoned thus: FIRE ESCAPE ONLY. WARNING-- ALARM WILL SOUND.
I stepped out the door and looked down along, steep slope into the canyon of the Turnpike.
The American Megaversity Campustructure was three blocks on a side, and squatted between the Megalopolitan Turnpike on the north and the Ronald Reagan Parkway on the south. Megaversity Stadium, the only campus building not inside the Plex proper, was to the west, and on the east was an elaborate multilevel interchange interconnecting the Pike, the Parkway, the Plex and University Avenue. The Pike ran well below the base of the Plex, and so as I emerged from the north wall of the building I found myself atop a high embankment. Below me the semis and the Audis shot past through the layered blue monoxide, and their noises blended into a waterfall against the unyielding Plex wall. Aside from a few wretched weeds growing from cracks in the embankment, no life was to be seen, except for Casimir Radon.
He had just emerged from another emergency exit. We saw each other from a hundred feet apart, waved and walked toward each other. As we converged, I regarded a tall and very thin man with an angular face and a dense five-o'clock shadow. He wore round rimless glasses. His black hair was in disarray as usual; during the year it was to vary almost randomly between close-cropped and shoulder-length. I soon observed that Casimir could grow a shadow before lunch, and a beard in three days. He and I were the same age, though I was a recent Ph.D. and he a junior.
