interior of a long, narrow structure with a metal roof supported by a framework of metal beams and supports. A large fan hangs from the roof. The floor is dark and dirty, with some scattered debris. The sides of the structure appear to be open or partially covered, with glimpses of the outside visible in the distance. The perspective is from one end of the structure, looking down its length.
