I left because there were no jobs in Michigan, and the Sun Belt seemed to be thriving by comparison. A secondary reason had to do with long, cold, snowy winters. Is it better here? Yes, I think so, although nowhere is good in this depressed economy.
I have two sons who were born and raised in Georgia, and I bought a small farm here almost three years ago. I have two sisters back in Michigan, as well as many friends, and I go to visit every few years, but I will not move back there.
