No Freeze Zone

We're looking at properties down south and one of the areas we're looking at are the Carolinas. I told my husband today that we should plan some vacations over the next few season to various areas we are interested in. We could, for instance, look into reservations at some rentals and get a feel for the surrounding areas in North Carolina. The cruise down the coast to Florida. We had considered Virginia, but then decided nothing further north that one of the Carolinas. I am serious about wanting to move to a 'no freeze zone.'
