There are two more pieces of advice I would like to give.
First, have you decided on a major? What do you want to study? Make sure that whichever school you pick has a good program in your major. And, going deeper than that, try to examine yourself as to why you want to go to the school you do. If you were a little kid and wanted to go to UCLA, you could examine yourself (your goals, what you are hoping to get out of your college experience). Sometimes your expectations can change, and what you wanted as a younger person is no longer valid. Only YOU can decide what it is that YOU want.
Secondly, always try to find out about the coach, what their philosophy is, and always talk to athletes who are on the team now. That's very important. Is the coach a screamer, or is he/she more laid back? What is the tone on the team? Do the runners all get along and help each other, or is it more competetive--competetive even at practices? Don't attend college blindly. You should understand going in what your role will be. If you end up being 9th woman, say, on your cross country team, will you get to travel to away meets, that sort of thing? Sometimes there are pecking orders on teams. It can be discouraging to be on the second tier in the pecking order, watching all the first tier women getting all the perks, when you're used to being at or near the top. Having some idea of what your adjustment will be once you get there will help you decide and then to be successful once you're there. You may not make varsity your freshman year, but could be on varsity by your sophomore year.
Your mileage and training seems very good for high school. Realize you will probably train harder in college than you are now, and that will be an adjustment too.
I can understand you not necessarily wanting to go east (for Ivy League or whatever). A runner like Sara (Bei) Hall would probably have struggled if she had gone east because she doesn't like cold weather. I just wanted you to see that you are right in there with many of the girls that make those teams (not at the top, but in a good position to be accepted to those schools and make those teams).
Keep academics at the forefront when considering prospective schools. When you apply, if you can convince the admissions people that you can take advantage of what they offer at their particular school, that will improve your chances of getting in.
