My plan to retire at 60 is still in place, and that's now less than 12.5 years away.
As my username suggests, we are IN Ohio but do not plan to retire in Ohio. This winter has solidified that idea even more. I actually like Ohio for many reasons, but the weather just is not good.
My wife and I prefer warmer temperatures, so a southern or southwestern state is likely. We really like Arizona for many reasons, but the water issue is a serious one, and they have political issues and drug trafficking issues that might keep us from going there. So, short of that, New Mexico is a possibility. Tennessee is also a good choice. We would also consider North or South Carolina.
As my children get older though and the reality that they won't be living with us all that much longer sets in, I can see staying in Ohio if they both do and start families here. If that happens, then we will bolt town anytime a super cold spell moves in.
