Retirement, if by choice means that you already made it. Congratulation and so you can live anywhere in the country, whether the tabs are higher than the rest.
If retirement like in a force kind of a thing and I did not plan for retirement then I'll go live with the best child that is for me. Wherever he goes is where I will go. I'll bum in his house and eat off his food and I don't boss anybody around so that his wife and I can get along. If he wants privacy, get me an RV and I'll park it in his backyard. I'll turn my RV into a cyber cafe living and I'll be a hacker. You can get a kit house for $50k which is not too bad.
