Camaraderie, we won't be there all the time (we don't live full time in Beaufort, unfortunately!), but I am there a couple of times a month throughout the winter, and am close enough to run over for hurricanes or freezes. And we will have shore power, but I don't know that we would leave it hooked up unless we were there -- don't know a lot about that, but would think you wouldn't want to expose yourself to surges or bad wiring unless you were there to have a quick remedy? All that said, probably a pretty thorough winterization would be in order just in case...
