The Villages Lightning Study Group which Len Hathaway leads gives presentations all through the year at club meetings, special meetings organized by local residents interested in lightning and at the POA meetings. Here is the link to the POA meeting since it was recorded. It will explain all the information about lightning and surge protection and the problem with the flexible gas lines used many years ago and what to do about it.
