An accumulation in one corner indicates the city's rubbish disposal depot resides on the other side of the lot's wall. Layers of grease, sludge and similarly unpleasant liquids decorate the sandstone's surface like an artist's splatter painting. The stagnant stink invades every nook and cranny while loitering in the air like a putrid fog.
