Randy could never understand why everything smelled so bad until he came upon a large, crisp rectangular hole in the sidewalk, and stared down into a running flume of raw sewage. The sidewalks are nothing more than lids on the sewers. Access to the depths is provided by concrete slabs with rebar lifting loops protruding from them. Squatters fashion wire harnesses onto those loops so that they can pull them up and create instant public latrines. These slabs are frequently engraved with the initials, team name, or graffiti tag of the gentlemen who manufactured them, and their competence and attentiveness to detail vary, but their esprit de corps is fixed at a very high level.
