I am near Ellsworth as well and actually ended up cancelling my flight plans that I had on christmas eve because we lost power. With no estimates on the return of power I did not want to leave the house unattended in fear of burst pipes (did not have RV antifreeze or time to winterize the house). We have wood stoves and a generator so maintaining temps while here is no issue.

All good advice, I go one further anytime I leave the house for more then a day or so I always turn the well pump power off (summer or winter) and open hot and cold water.
