I could not agree with Marc more! Megger the whole place! Make sure that every switch is closed and test each 3 and 4 way switches in all states. That stuff will burn holes in NMD90 all over the house. Make provisions on the time this will take in your requote
If that lightning shot was trying to get to ground from a 60' feeder it is no wonder it started taking every other path available. I have an air terminal directly above my weather station 18' above my roof. That took a direct hit and I only lost the serial port in the PC and the weather sender on the other end. They both almost work but they were wounded. I bet if the station wires were not so close to the conductor down to the ground rod I wouldn't have lost a thing.
