Does the move have to be permanent? If not, could you set things up so that you have a five-year stretch, and then see where you're at? A lot can change, for worse and for better, within five years.
It sounds like you're very keen to move and looking for reasons why, rather than reasons why not.
To be fair, and to balance my previous post, there is a lot that I do miss.
I miss the range of classes and opportunities for activities that were offered at my high school, and that are still offered at a lot of schools. My cousin's kids still get to star in school productions and play on school soccer teams. My own high-schooler in Scotland has nothing but exams. I miss the broad general education: I think my own high-schooler is missing out with the way subject exams and university entrance is set up here. If I could afford to send her to uni in the States, I would consider one in a good state.
I miss being able to get annual checkups at the doctor's office and I never understood why the NHS won't do these. I miss children being able to see a pediatrician, rather than a GP who may or may not have an interest in children's health.
The range of food (including fresh) that my parents get at their local grocery stores is so much broader than what I can access. I miss store bakery Italian bread. If there's a Winn Dixie near your new neighbourhood, the cakes are amazing.
I miss being able to swim in the sea, in ponds, in outdoor pools. The spring, summer, and autumn climate should allow you to do more outdoors.
Having family close by sounds like you'll have help getting to grips with everything.
Big things like time off, abortion rights, health care expenses, the risk from guns ... all of those things are real and haven't gone away. Thinking of those risks as just a "hick state" problem isn't wise. The Newtown primary school massacre took place in Connecticut. The people who want abortion banned in the hick states want it banned everywhere.
I would also advise caution about knowing your employment rights. If the working parent ever gets laid off, you may not be entitled to a notice period or severance. Depends on state law and company policy, IIRC. Something you can think about and prepare for, in any case.
