THE LADDER ========== The ladder is made from square steel tubing and old telephone cable. It descends through concrete, then through a section of black seamless material that has no visible seam or anchor. Halfway down, you can still hear the Garage fan. Farther below, you hear relays working in a pattern that almost resembles rain. A red mark beside the rungs reads: SURFACE MAINTENANCE / 608 Below it, somebody has scratched: THIS IS NOT A BASEMENT
