For a solid 24 hours we heard the constant crack of branches breaking and then falling from the trees. The ice on the power line caused them to break, resulting in our loss of electrical power. When our power went out, we turned out to be fortunate. We were only without power for only 30 minutes. Some friends of ours in the city were less lucky, as they were without power for an hour and a half. When their power went off, they were using their computer and the hard drive crashed. They lost all of their data and have to replace the hard drive. Still other people were even less lucky. Those, living in the country were without power for as long as a week. We really felt sorry for them. Many of them were farmers who had baby pigs that needed heat. Fortunately many of them owned gasoline powered generators.
