I am gonna give a few more reasons for Indiana, specific to opportunities. I'm not saying other states don't have these, I'm just saying they're amazingly plentiful in Indiana.
1) Spectacular rookie regional, growing more next year
This regional was organized by a team of college students and professors and highschool teachers, not by a company. It was tailored to students' interests and needs and had multiple socials and immense academic opportunities. Huge points for fun, fairness, and organization.
2) Science is a priority
Every state has great job availibility, but go talk to some students doing internships in Indiana. There are so many of them out there, and there are many many opporunities for highschool and college students. Indiana is not just some farm state.
3) Growth of teams
To my knowledge there is not yet outsourcing going on with Indiana teams. Why is that? Because so many companies want to see good students stay in state, and help in the future. There are many many upcoming teams from Indiana, so just you watch!

I live here. We give good hugs.
