Lightning

At this time of year and in the summer, I regularly check on the possibility of nearby storms. If there is a chance of danger, I disconnect antennas and power sockets "just in case". Years ago one of my work colleagues house, on a very ordinary housing estate, was struck by lightning and he suffered great damage. Ever since, I have been a bit paranoid. OK a direct strike is rare, but power surges can and do occur.
