Adding that your interests outside of medical school (and within) matter on campus preference too.
A few of the campuses share with large schools, so if the College Sports Life is appealing -- two BIG TEN campuses, and Notre Dame are all promising.
Terre Haute is very rural, so there's that.
Fort Wayne, South Bend, Gary, and Indianapolis will give you most racial and ethnic diversity for living and for patient populations (however you want to look at it).
Northern locations = more access to the great lakes, Indiana Dunes, Indiana Beach and if you're into cars = northern Indiana is a place to be.
Southern locations = i mean...who doesn't love a good view of the Kentucky border.
The Caves and National Parks are also somewhere in the state (if you're a nature go-er).
