What is the setting in Ralph Ellison's"Battle Royal" from The Invisible Man?

The major setting of "Battle Royal" by Ralph Ellison is the ballroom of the hotel where the narrator and his schoolmates go to participate in a boxing match.  In the ballroom, a temporary boxing ring has been erected and there are seats around the ring.  There are many white spectators in the crowd, and the atmosphere in the room is tense. 

In other parts of the story, however, the action takes place in the narrator's home and in the realm of his dreams.
