What to do in Tallahassee

Hi Lindsey,
It seems the decision is already made.
If you like, I can give you my view on what to expect in the southeastern US from an European perspective.
There are many good reasons to move to the US, one of them are good economic opportunities. The other is more freedom to pursue your own aspirations.
I came to this country in the tender age of 33 in 1991. The beginning was rough, but all in all it turned out well in the long run.
If someone has an open mind and is willing to take some risks, the US is still a good destination for some immigrants and life here can be rewarding.
However, Northern and Western Europeans may find Small Town USA tough to get accustomed to, especially the conservative South. In comparison attitudes in New England and the West Coast are quite different.
Social interaction outside of work is generally limited, many Americans try to find social contacts through religious organizations. The bar scene is predominantly for hooking up, not necessarily just a place to hang out. Trying to find like minded people isn't always easy, because people work longer hours than most Europeans do. Also extended vacations are not common, you can expect 2 weeks per year in the US.   
For the climate, the summers in GA are stifling hot and long. It may take some getting used to living in a small, landlocked southern town with little to do.
The healthcare system is very different from the British NHS. A typical healthcare plan here gives you access to providers within a specific network. In case of a medical emergency where you have been taken to an out of network provider, it can get very tricky with what you may end up paying yourself. Also expect bills to be obscenely high even for the most ordinary of procedures. Even in a best case scenario, expect to battle it out financially with your health insurance and all individual providers involved with your treatment. So focusing on getting well isn't the only thing to deal with.
Lindsey, I hope this is helpful to you and your husband and not too discouraging! I wanted to point out some issues to be aware of.
I wish both of you the best of luck with your adventure and please feel free to contact me again if you think my advice may be of help.
Cheerio,
Stephan
