the wrecking yard could be a metaphor to a "place" inside a person's head where their bad memories are stored and must be wrecked and gotten rid of, forgotten.
the person "walks through the wrecking yard"...aka strolls through memory lane and cannot let go of the horrible memories and is therefore depressed, living in their bad past. and they talk about it all the time (gather round to hear this tale, a story which has grown old)
