This dark hallway feels much like a cave.  Its ceiling is at least fifty
feet high and its walls are perforated, creating possibly millions of
storage receptacles.  Each hole is snuggly filled with pale yellow boxes
garnished with red bow ties.  Two towering ladders on wheels ascend each
wall, allowing an attendant to store or retrieve any box regardless of
location.
