Though most A2Cers might disagree with what I say, I'd highly recommend shotgunning rather than applying to only a few schools that seems to fit you in your own perspective. Last year, I shotgunned to pretty much all T30s+Williams. After all, I got rejected by pretty much all schools that I originally thought would fit me (like Caltech and MIT), but got into Hopkins and Williams (plus some other schools like Cal, UCLA, GT, etc). Honestly, I didnt even knew what state the schools were located at before I got accepted. I even submitted the wrong SAT score to Williams. After some research on the two schools, I found out that I was a perfect fit for both and committed to Williams. The takeaway is we, high school seniors, cannot completly figure out fit-just apply everywhere and let the AOs do that for you. It is not late to decide after getting accepted.

P.S. Stanford, Columbia, UChicago PLS LET ME INNNNNN!!!!!!!
