Trans-Atlantic
Started this story back in Colorado, and finished it in Glasgow, with writing in Chicago and over the Atlantic and Manchester and over Scotland along the way.
The biggest worry about being "clever" in writing is never being quite sure how obvious one is. Too obvious, and the audience simply groans. Not obvious enough, and they just scratch their heads and you're never quite sure why they missed the mark, and damned if you can just explain the joke ...
No joke in "Saturday Night Rush," though it turned from a Leilani story about the (very real, if you've ever experienced it) restaurant meal rush into something about a pair of characters who, if I've done my job right, the reader figures out, oh, three-quarters of the way through, with a loud, "Ohhhhhh!"
It was fun to write, and if the opportunity arises, I may actually do something further with them in the story being told. Though, in general, I hate screwing with the meta-flow of these things (believe it or not).
Many thanks (though the indirect inspiration was not recognized until after I'd gone down this road a ways) to Neil Gaiman.
