An ice cube on the shelf will tell you how much melting went on during a power outage while you are gone. This power outage did not affect my frozen food. Whew!
NB, I am not sure about the generators. I do know of a few that have them, but am not sure how they are used. These folks do not yet have power to their places. Another down the way must have one because they have wintered a couple times on the island.
FLL, no thanks on the wind farm on Rattlesnake IS.
