Where to get away from Minnesota Winters

Everything is relative, and it depends on your interests. That being said; the Southeastern states are close together, have excellent choices for food, shopping, weather, shoreline, historical, etc. The Gulf states have a regional flavor that transcends everything else, and very historical, unique economy, and shorelines of Gulf, rivers, and swamps. The Southwest has the desert, the mountains, the wide open spaces, the unique food, and interesting people. Each areas have RV parks which cater to retirees, and you might find bargains for a monthly stay. I would not plan more than a month at a place, because you want to explore alternatives. Perhaps concentrating on a geographical area of the country each of the first few years, and then narrow it down after that.
