I'm from Michigan and I love it. I can't imagine being somewhere without 4 seasons. Fall is beautiful, especially the farther north you go. Winter, too, is beautiful and not THAT cold (granted, I'm not from Florida). Summers can still be really hot and humid--so then you'd feel at home! Oh, and spring is really good too. Plus, you have the Great Lakes. And good beer. Really good beer.
What city is it in? Just curious.
I'm also having similar doubts and fears, and it's with a program that I'm not totally in love with....
Good luck!
