Why you want to go to a particular school seems like a personal thing. If YOU can't think of any reasons (without help) why you should apply, then maybe you shouldn't. Go to the websites (you said you did this), check out their entries in the MSAR, and other guide to medical schools-type books. Look at the type of curriculum, research, location, etc.. If you're applying to these schools as backups and have no interest in actually attending them, maybe you should rethink that.
