Final answer:
The text provided does not contain information about anything being hang dried outside David's room, hence, it's not possible to answer this question accurately.
Step-by-step explanation:
The content loaded regarding what was being hang dried outside David's room is not provided within the excerpts you presented. To know what was outside David's room, the context from the text would be necessary, and this seems to be a case where details were expected from a specific story or book. Since the provided text does not directly mention any items being hang dried outside a room, particularly not David's, it is not possible to give an accurate answer to this question based on the given reference material.
