Thanks for the replies, I'll start looking into those options.
Just out of curiosity, are lightening storms able to be forecast with some degree of accuracy and forewarning? It appears that Washington state has the fewest cloud-to-ground strikes of any state in the country (Florida has the most) so I don't have any first hand experience with them.
Also, while looking around online for lightning info I noticed that many ground strikes hit trees. In one case semi-locally a strike hit and shattered a very large tree. I was always under the impression that a ground strike would seek out things like antennas and other metal or elevated metal structures? The house near this tree had what appeared to be a number of such metal protrusions on the roof yet was unharmed.
