I am originally fom Texas, been here almost 12 great years!
A few things to consider before moving here:
The weather. There is snow and some years there is LOTS of it. Most years there is lots of cold as well. I'm talking 10 degree below or lower. I happen to love the snow, so that wasn't much of a problem for me.
That is the biggie for a lot of Southerners after they move here. They hate the cold and snow, then they start to hate a truly wonderful state. I am proudly from Texas, but Wisconsin is my home. I will never move back to Texas. You will find that the Packer fans are just a rabid as Cowboys fans about their team.
There is a diverse population here and you will learn about Mennonites, Amish, Hmong (from Laos), German, Polish, and we are getting an increase in the Mexican/Latin as well.
I don't where in Texas you are, but the scenery here where I live is much like the part of East Texas that I'm from so I don't miss the land as much as some others I have known.
You have all four seasons here most years. Although it can be classified as 2: Winter and construction. The ground freezes too hard in the winter for any road work to be done so it gets squeezed into late spring, summer, and early fall.
Most hospitals aren't union up here. At least not the ones I am aware of. I don't know alot about the bigger hospitals in Madison or Milwaukee, but here in the center of the state we don't have them.
I work in a large teritary care hospital smack dab in the center of the state and for the most part love what I do. Of course, we all know that there are days when you could take it or leave it.
We have a NICU here that is amazing, the PICU is great, Cardiology care is among the top in the nation and our associated clinic is world-renown.
I really love this state and the people in it. If you need anything more specific, feel free to PM me.
Good luck and best wishes in your decision.
