Here at Terribly Write headquarters, we’re betting that the “news editor” for Yahoo! Style has no idea that there is a word hangar that is very different from the word hanger.
Every time this “editor” has described the venue, she refers to it as a hanger. A hanger is a device for storing clothing in a closet. A building for storing aircraft is a hangar. And that’s where this ball was held — in a converted aircraft hangar. (Oh, I almost forgot: cover should be covered. But I quibble.)
