When you see a gorgeous woman dressed in a strapless black dress made entirely out of feathers hovering a good three feet above the sidewalk, with gorgeous black wings stretching out five feet to either side of her, what you think is going to depend on where you are. If you're in Vegas, you'll think she's advertisement for a pretty kick-ass magic show or maybe some kind of magic/risque dance act. If you're in New York, you'll think she's a model. If you're in Goodwin, Iowa, you'll probably think she's an angel of the Lord, or maybe one of those Goth teenagers trying to pull off a prank. If you're in Roswell, you may have an open mind about what she is or you may think she's an alien. If you see her in Chicago or Minneapolis or Boston or some other reasonably sized city, you may wonder what she is and assume she's some kind of city phenomenon, like an art car or a parade of naked painted people. The real fun comes when every assumption becomes right.
