one of my best friends moved to Texas a few years ago and his parent just retired and moved down their. From what they've told me they have good job availability and the cost of living is much lower than here in the northeast. Texas, Georgia and Wyoming are my top 3 states that I'm giving consideration to move too. I hear Arizona isn't bad either.
Gotta say after visiting Texas it is certainly one of my favorite states. I would love to move down their one day from my current state, which happens to be Massachusetts, but my family means far too much to me to leave them behind. Maybe when I retire, which is a loooooong ways down the road.
