County does not matter, per se. But some rural areas have less competition, and hence people with lesser stats may have a higher class ranking, etc.
But Newton13, I would say you are borderline. I could see the EC's being a bit too thin, and I'm not sure if the rest of your application will compensate for it. Is there any way you could retake the SAT, and possibly improve your score? I would consider that option.
But of course, please apply. You do have a good shot!
