And BTW, Huxley, IA...not that rural
I've been watching season four of Buffy, the Vampire Slayer, which used to be my least favorite season, but is growing on me (it's probably still my least favorite season, but it has lovely little gems like--'My contrition complete dwarfs the impending apocalypse.').
Anyway, in one of the episodes (Pangs, I'm thinking, since that's the Thanksgiving one), Riley says that he's from Huxley, IA, which I'm guessing is supposed to be really, really rural. And by some standards, I suppose it is. But I've got to say that I lived farther from airports and malls when I lived in western New York than people in Huxley, IA do. Huxley is ten minutes from Ames (fifth largest city in Iowa!) and half an hour from Des Moines (don't ask me how big Des Moines is, because then you'll just laugh).
If you want rural Iowa for your novel or screenplay, you should consider Lewis or Humeston or Maquoketa (Maquoketa isn't really that rural by Iowa standards, but it sounds cool--Ma-COKE-e-ta--and will make people think you know what you're talking about).
