I've also never visited the state... I actually thought I would be rejected as others have alluded to earlier. I dont think it makes any sense in swimbear's scenario because he definitely should have even been considered "in-state"... I actually think its the luck of the draw.

If you look at the website link (and click on Indiana University), it says that they interview ~349 OOS per season and actually accept ~179, so its definitely not impossible. Rather than simply numbers alone... I believe they try to find a fit for their school which is probably not the same as that of other schools. Besides that, i think it's about luck & perseverance - which is what this whole process seems to be about.
Good luck with your other schools... you'll definitely get into the school you want.
